Electromagnetic field plot of an inductive window by the moment method

摘要

A moment method is used to plot the electromagnetic field of an inductive window in a TE/sub 10/-mode rectangular waveguide. Green's dyadic functions are derived based on Tai's approach, which is a modified form of Hansen's vector wave functions. Based on the computed electric fields, the S matrix and the equivalent aperture reactance of the waveguide window are calculated. This calculation agrees with the previously published closed-form results of N. Marcuvitz (1964).
