Analysis of electromagnetic interference in two dimensional problems using the generalized multipole technique

摘要

A simple numerical solution is given for the problem of electromagnetic coupling through a dielectric-loaded slot on a conducting cylindrical shell of arbitrary cross section. The exciting source is assumed to be either an incident TM plane wave or an electric line source placed inside the shell. The solution uses fields generated by fictitious multipole line sources to simulate the fields of the slotted cylinder. The application of the appropriate boundary conditions yields a system of linear equations which can be solved for the unknown coefficients of the multipole expansions. The coefficients can then be used to obtain the desired field and other quantities of interest.
