Abstract

Abstract

Based on the fundamental solution of a two dimensional Helmholtz equation, the general principle of determing the cut-off frequencies of waveguides filled with two dielectric layers by using the boundary element method is discussed. In terms of the formulae obtained, some numerical results are given for two commonly used configurations. The results show that the me-od is simple and practical, and iis precision is appreciable.
