Credit is also due Mr. Doherty for suggesting the parallel impedance chart, and to Mr. Klyce for his suggested use of highly enlarge portions of the chart in determining bandwidth of resonant stubs. Trombarulo's investigations were helpful in writing sections dealing with the negative resistance chart. The early enthusiastic acceptance of the chart by staff members at MIT Radiation Laboratory stimulated further improvements in design of the chart itself. Credit for publication of the book at this time is principally due to encouragement provided by Messrs. Foster and E. Crump of Kay Electric Company [14]. Phillip H.

Accordingly, its design and many of its applications can best be described in accordance with principles of guided wave propagation.

The qualitative descriptions of the electrical behavior of a waveguide, as presented in this chapter, will provide a background for better understanding the significance of various interrelated electrical parameters which are more quantitatively described in the following chapter. As will be seen, many of these par~meters are represented directly by the coordmates and associated scales of a SMITH CHART, and their relationships are basic to its construction. under~tood to include not only hollow dylindncal unlconductor waveguides but all other physical structures used for ~iding electromagnetic waves except, of course heat and light waves. Included are multi-~ire transmission line, strip-line, coaxial line, triplate, etc. Waveguide terms as they first appear in the text will be italicized to indicate that their definitions are in accordance with definitions which have been standardized by the Institute of Electrical and Electronics Engineers [11], and are currently accepted by the United States of America Standards Institute USASI.

Also, terms and phrases are sometimes italicized in lieu of underlining to provide emphasis or to indicate headings or subtitles. Although it may ultimately be of considerable importance in the solution of any practical waveguide problem, the particular wave guide structure is of interest in connection with the design or use of the SMITH CHART only to the extent that its configuration, crosssectional dime~sions in :-vavelengths, and mode of propagatwn establIsh two basic electrical constants of the waveguide, viz. Both of these constants are further discussed in Chap. duc~ors in wav~lengths. Modes of propa? tion although only one will generally be selected for operation. Field patterns for the more common dominant mode in a two-wire and in a coaxial transmission line are shown in Figs. In this mode both electric and magnetic field components of the wave lie entirely in planes transverse to the direction of propagation, and the wave is, therefore, called a transverse electromagnetic TEM wave.

There is no longitudinal component of the field in this mode. As is the case for the waveguide structure, the mode of propagation does not playa direct role in the design or use of the SMITH CHART. Its importance, however, lies in the fact that each mode is characterized by a different value for the propagation constant and characteristic impedance to which the variables of the problem must ultimately be related. A specific waveguide structure may provide the means for many different modes of propaga- When the mode of propagation is known in a particular uniconductor waveguide, and operation is at a particular frequency, the waveguide EL. ECTRIC FIEL. O MAGNETIC FIEL. ECTRIC FIELD - - - - MAGNETIC FIELD - - Fig. The SMITH CHART can then be used in the same way in which it is used for problems involving the simple TEM wave in two-wire or coaxial transmission lines. A further discussion of the subject of propagation modes and their associated field patterns will not be undertaken herein since the reader who may be interested will find adequate discussions of this subject in the literature [32, 52].

If a continuously alternating sinusoidal voltage is applied to the input terminals of a waveguide, a forward-traveling voltage wave will be instantly launched into the waveguide. This wave will propagate along the guide as a continuous wave train in the only direction possible, namely, toward the load, at the characteristic wave velocity of the waveguide. Simultaneously with the generation of a forward-traveling voltage wave, an accompanying forward-traveling current wave is engendered, which also propagates along the waveguide. The forward-traveling current wave is in phase with the forward-traveling voltage wave at all positions along a lossless waveguide. These two component waves make up the forward-traveling electromagnetic wave. In the case of a uniform waveguide it is called, specifically, the characteristic impedance. The input impedance has, initially, a constant value independent of position along the waveguide.

Its magnitude is independent of the magnitude or of the phase angle of the load reflection coefficient, it being assumed 11 that in this briefinterval the forward-traveling electromagnetic wave has not yet arrived at the load terminals. At any given position along the waveguide the forward-traveling electromagnetic wave has a sinusoidal amplitude variation with time as the wave train passes this position. This is due to the distributed series resistance of the conductor or conductors and to the distributed shunt leakage resistance encountered, respectively, by the longitudinal currents and the transverse displacement currents in the dielectric medium between conductors. This dissipation of power is called attenuation, or one-way transmission loss.

Attenuation does not change the initial input impedance of the waveguide as seen by the forward traveling wave energy as it progresses along the waveguide, since it is uniformly distributed, but it nevertheless diminishes the wave power with advancing position along the waveguide. Attenuation should not be confused with the total dissipation of a waveguide measured under steady-state conditions, as will be explained later. Upon arrival at the load, the forward traveling voltage and current wave energy will encounter a load impedance which mayor may not be of suitable value to "match" the characteristic impedance of the waveguide and, thereby, to absorb all of the energy which these waves carry with them.

There will then be no reflection of energy from the load. In this case the forwardtraveling wave will be the only wave along the waveguide. A voltmeter or ammeter placed across, or at any position along the waveguide, respectively, would then indicate an rms value in accordance with Ohm's law for alternating currents in an impedance which is equivalent to the characteristic impedance of the waveguide. difference of more than one-half wavelength between reflected and incident-wave energy , the relative phase angle of the voltage reflection coefficient only is usually of interest. This is obtainable by subtracting the largest possible integer multiple of corresponding to integer lengths of one-quarter wavelengths of waveguide from the absolute or total phase angle of the voltage reflection coefficient, to yield a relative phase angle between plus and minus If, on the other hand, the load impedance does not match the characteristic impedance of the waveguide, and therefore does not absorb all of the incident electromagnetic wave energy available, there will be reflected wave energy from the mismatched load impedance back into the waveguide.

This results in a rearwardtraveling current and voltage wave. The complex ratio of the rearward traveling voltage wave to the forward-traveling voltage wave at the load is called the voltage reflection coefficient. Likewise, the complex ratio of the rearward-traveling current wave to the forwardtraveling current wave at the load is called the current reflection coefficient. If the waveguide is essentially lossless, the magnitude of the voltage reflection coefficient will be constant at all points from the load to the generator and will be equal to the voltage reflection coefficient magnitude at the load. If there is attenuation along the waveguide, the magnitude of the voltage reflection coefficient will gradually diminish with distance toward the generator, due to the additional attenuation encountered by the reflected-wave energy, as compared to that encountered by the incident-wave energy in its shorter path.

Thus, there will appear to be less reflected energy at the input to such a waveguide than at the load. The traveling current waves on a waveguide, which accompany traveling voltage waves, will likewise be reflected by a mismatched load impedance. The magnitude of the current reflection coefficient at all points along a waveguide is identical to that of the voltage reflection coefficient in all cases. The phase angle of the current reflection coefficient at any given point along the waveguide may, however, differ from that of the voltage reflection coefficient by as much as ± depending upon the relative phase changes undergone by the two traveling waves at the load. The voltage reflection coefficient will also vary in phase, with position along the waveguide. The phase angle of the voltage reflection coefficient at any point along a waveguide is determined by the phase shift undergone by the reflected voltage wave in comparison to that of the incident voltage wave at the point under consideration, including any phase change at the load itself.

The voltage and current reflection coefficient magnitude at the load will both be unity in this case. The phase angle of the voltage reflection coefficient at the load will be zero degrees under this condition, since the same voltage is reflected as a wave back into the waveguide at this point. However, the current reflection coefficient phase angle at the open-circuited load will be ° since the incident current wave amplitude upon arriving at such a load will suddenly have to drop to zero there being no finite value of load impedance and will build up again in opposite polarity to be relaunched as a reflected wave into the waveguide. The collapse of the magnetic field attending the incident current wave, when it encounters an open-circuited load, results in an accompanying buildup of the electric field and in a corresponding buildup of voltage at the open circuited load to exactly twice the value of the voltage attending the incident voltage wave.

The reflected wave voltage builds up in phase with the incident wave voltage and the voltage reflection coefficient phase angle is, accordingly, zero degrees at this point. The modified load voltage now launches back into the waveguide a rearward-traveling voltage and current wave in a manner similar to the initial launching of these waves at the generator end. These rearward-traveling waves combine with the respective forward-traveling waves and, because of their relative phase differences at various positions along the line changing phase angle of voltage and current reflection coefficients , cause alternate reinforcement and cancellation of the voltage and current distribution along the line. This phenomenon results in what has previously been referred to as standing or stationary waves along the waveguide.

The shape of these standing waves with position along a waveguide is shown in Fig. It will be seen that their shape is sinusoidal only in the limiting case of complete reflection from the load, i. A graphical representation of the combination of the two traveling waves is shown in Fig. Upon arrival back at the generator terminals, the rearward- traveling voltage wave combines in amplitude and phase with the voltage being generated at the time, to produce a change in the generated voltage amplitude and phase. At this instant, the generator is first presented with a change in the waveguide input impedance and readjusts its output accordingly. This is the beginning in time sequence of a series of regenerated waves at each end of the waveguide, which after undergoing multiple reflections therefrom, eventually combine to produce steady-state conditions and become, in effect, a single forward-traveling and a single rearward-traveling current and voltage wave. Thus, in practice, it is not usually necessary to consider transient effects of multiple reflections between generator and load beyond that of a single reflection at the load end of the waveguide.

The magnitude and phase angle of the voltage and current reflection coefficient bear a direct and inseparable relationship to the amplitude and position of the attending standing waves of voltage or current along the waveguide, as well as to the input impedance or admittance at all positions along the waveguide. Through suitable overlays this relationship can very simply be described on the SMITH CHART. As a specific example of this relationship, the magnitude of the voltage reflection coefficient at the open-circuited load previously considered is unity. Its phase angle is zero degrees. The accompanying standing voltage wave has a maximum- to-minimum wave amplitude ratio of infinity. The position of the maximum point of the voltage standing wave is at the open-circuited load terminals of the waveguide, at which point the input impedance is infinity. Expressed algebraically, in terms of the amplitude of the incident i and reflected r traveling waves, the standing wave ratio S is seen to be their sum divided by their difference, Le.

Oto 00 as is more customary in this country, and the circular coordinates are distorted to permit this standing wave ratio scale, rather than the reflection coefficient scale, to vary linearly from unity at the chart center to zero at its rim. This, in effect, radially expands the region near the center of the conventional chart and radially compresses the region near its rim. The other transformation of the usual SMITH CHART coordinates Fig. This transforms the circular central region to a band adjacent to the perimeter, and vice versa; no radial expansion is provided, however. The first of these is shown in Fig. This chart is suitable for displaying waveguide input impedance or admittance characteristics accompanying mismatches which produce standing wave ratios less than 1. The chart of Fig. It is suitable for displaying waveguide input impedance and admittance characteristics accompanying very small mismatches standing wave ratios ofless than 1.

Like the complete SMITH CHART of Fig. The peripheral scales are unchanged from those on the complete chart, and indicate distances from voltage nodal points when used to display impedances, and distances from current nodal points when used to display admittances. The radial scales have the same center values as those for the complete chart but are linearly expanded by the radial expansion factors indicated above. Similarly, Fig. At the scale size plotted in Figs. radius of the coordinates of a complete SMITH CHART would be Figures 7 A and 7. The regions of the SMITH CHART shown in Figs. frequency of waveguide stubs operating near resonance or antiresonance [20]. In Fig. These curves trace the input impedance or input admittance locus on the enlarged chart coordinates as the frequency is varied within ± 1. Due to the high degree of enlargement of coordinates the dotted spiral curves closely approximate arcs of circles centered on the All such plots require only straight lines and circles for their construction.

The outer boundary of such a construction corresponds to the boundary of the SMITH CHART coordinates. As shown in Fig. determines the angle a as measured from the horizontal RfZo axis. i~c ~ v IV ~ "'-V When negated, the decibel form is referred to as the return loss. Does this agree with the value reported by Yes, fortunately. The top hemisphere of the chart represents inductive admittance, which is negative. The admittance grid value of the point is 0. When multiplied by the normalizing admittance of 0. The value of a point on the impedance grid reflected about the center of the chart is 0. This straight-line method may be used to find equivalent admittances on conventional impedance SMITH CHARTS. The length of this vector is the magnitude of the voltage reflection coefficient, rho. The angle of this vector with respect to the real axis is the angle of the reflection coefficient with zero degrees to the right and degrees to the left. What portion of the SMITH CHART corresponds to a reflection coefficient magnitude of I?

What range of reflection coefficient angles is generated by purely reactive loads. Solve Eqs. The voltage standing wave ratio, VSWR, is given by Eqs. Answers to Exercise 0 A reflection coefficient magnitude of 1 represents total reflection and corresponds to purely reactive loads on the circumference of the SMITH CHART.
