Integral Equation Method for Calculating Irregular Waveguides Using the Generalized Lorentz Lemma

Resumo

A method for solving boundary value problems for irregular waveguides that combines the generalized Lorentz lemma with a collocation technique is proposed. The method allows one to reduce boundary value problems to systems of integro-differential equations, which are algebraized by identifying collocation points with the points of localization of auxiliary sources.
