“…James and Walker [6] reported the analysis of a circular waveguide with a sinusoidally modulated transverse cross-section along the direction of wave propagation. Mallik and Sanyal [7] reported a similar analysis for the rectangular waveguide, for the dominant TE,, mode. The analysis uses a coordinate transformation based approach.…”

“…We have shown in the previous sections how the effective cross-section concept [S] can be combined with the coordinate transformation approach [7] to obtain the characteristics of rectangular dielectric waveguide with periodically and slowly varying width. The validity of the results can be checked by using the cascaded uniform transmission line matrix analysis of a single cell.…”

Wave propagation along a rectangular dielectric waveguide with slowly varying width has been studied using a transformed coordinate system and an effective cross-section approach. The associated differential equation has been solved using numerical analysis and Hill's analysis. The computed results have been verified using the cascaded transmission line matrix analysis of the structure in the original coordinate system. The agreement is found to be excellent. Many properties of the modulated periodic structure, for example, the propagation constant, the phase and the group velocities, the axial dependence of the Ell mode, and the space harmonic, have been studied. The results and the method will be useful in computer-aided design of dielectric waveguide phase shifters and filters. 0 1995 John Wiley & Sons, Inc.

“…As expected, the value of L sh or C se becomes infinite when the frequency approaches zero. Interestingly the same problem has been solved for a rectangular waveguide with sinusoidally varying width but by another approach rather than the small reflections [14]. However, the results are the same.…”

Abstract-The dispersion relation is derived for the most general configuration of a passive and reciprocal periodically loaded transmission line in a unique and simple form by introducing two novel parameters. Based on this relation, the phase and group velocities are determined and a simple condition for phase reversal propagation is obtained. The two above mentioned parameters help us to develop a polar diagram to model the behavior of any two-port network as a function of frequency. By this diagram, we can determine the direction of the phase velocity and also the value of the propagation constant. Then, symmetrical cells and thereof the periodic structures composed of them are analyzed. For such structures, it will be shown that the dispersion relation can be rewritten in a form similar to the Lorentz transformation. We design and analyze a bandstop filter to verify the method.

Abstract-This paper presents the analysis of linear tapered waveguide. Voltage-standing-wave-ratio (VSWR) is obtained from transmission matrix of the taper waveguide. Taper section is divided into number of section having uniform length. Transmission matrix of taper waveguide is found by multiplication of transmission matrix of each section. Transmission matrix of each section is obtained as the product of three matrices. One is of the initial length of transmission line, second one is due to discontinuity and third one is of the final length of transmission line. Transmission matrix of discontinuity is obtained by two methods. One is by equivalent circuit of step discontinuity and another is by moment method. The results are seen to be in good agreement with [1,2] and [3].
