Aperture field estimation in waveguide circuits for non-sinusoidal, periodic excitation

In this paper an attempt has been made to analyze waveguide circuits for non-sinusoidal, periodic excitations. The excitation functions, taken as example, are trapezoidal and clipped sine wave in nature and the waveguide circuit, that has been considered, is two interacting thick inductive irises. The excitation functions have been expressed in terms of Fourier series. The circuit has been analyzed using Multiple Cavity Modeling Technique and finally the normalized electric field distribution at the apertures have been calculated and plotted.
