К решению задачи дифракции резонаторных мод на поперечной щели проекционным методом

Abstract

The problem of an electromagnetic field diffraction of a volume coaxial resonator azimuthally dependent mode on an internal transverse ring slot and cylindrical dielectric is considered. For its solution the method of fields decomposition by simple modes of the resonator without a slot is used. The discretization of integral Fredholm equations for field functions on a slot is carried out with the help of the projecting Galerkin method. The application of the system of sine basis functions for this purpose is substantiated which does not yield field singularities on borders of a slot.
