Full Wave Analysis of a Trapezoidal Transmission Line using the Boundary Element Method

A full wave analysis of a transmission line with a trapezoidal cross section is described. The boundary element method (BEM) is used, and by making a convenient choice for the dyadic Green's function the method is shown to be very efficient in comparison to appropriate alternative methods of analysis. This is an innovative application of the BEM to an innovative structure. The analysis is verified by comparisons with calculated results from a vector finite element computer program.
