摘要

A new method is introduced to analyze arbitrary Longitudinally Inhomogeneous Waveguides ( LIWs). In this method, the integral equations of the LIWs, converted from their differential equations, are solved using the method of moments ( MOM). It is assumed that the electric permittivity function is known at all or only at some points along the length of LIWs. The validity of the method is verified using a comprehensive example.
