An Integral Equation for the Surface Current in the Problem of the Natural Modes of a Waveguide Containing a Resistive Film

Abstract

This paper considers the eigenmode problem for a waveguide with a resistive film. An integral equation for the surface current on the film is formulated. A method for evaluating the kernel is described, and an explicit expression for the kernel is derived for rectangular and circular waveguides.
