Excitation of plane-parallel waveguide with variable wall impedance
Abstract
Arbitrary 2-D excitation of plane-parallel waveguide with wall surface impedance varying arbitrarily the length of the guide axis is analyzed. Integral equations are derived for the guide field spectral densities with the aid of Fourier integral transforms and the 2-D Green's function. Impedance variation patterns considered include: periodic, constant, stepped, and latticed (impedance filaments on a constant-Z plane). Analytical and numerical solutions of the Fredholm equations (of the 2nd kind) for those cases are considered.
