Green's functions for vertical current sources embedded in uniform waveguides or cavities filled with multilayered media

Abstract

A modal series representation of spatial‐domain electric field Green's functions for arbitrarily oriented electric current sources embedded in shielded multilayer media is presented. The Green's functions associated with planar excitations are briefly recalled, and the method to compute them is generalized to vertical current sources, yielding new components of the Green's function necessary for the analysis of vertical metallizations embedded in waveguides or cavities. © 2002 Wiley Periodicals, Inc.

Investigations on radio-frequency components and the multipactor phenomenon in high-power space applications

“…The starting point for the study of electromagnetic radiations in an enclosure scenario is the formulation of the electric and magnetic Green's function [39,40,41,42,43,44]. In this sense, an expression for the dyadic Green's function for waveguide regions is derived in Chapter 2.…”

“…The dyadic Green's function is defined as the fields produced by a unit dipole within the structure under study [42]. The study of Green's function arising in electromagnetic problems is a primary subject extensively treated in the technical literature [39,40,41,42,43,47 ]. Here we present a modal formulation of Green's functions for uniform, lossless waveguides.…”
