On the Application of Numerical Methods to Hallén's Equation: The Case of a Lossy Medium

A previous paper (Fikioris and Wu, 2001) analyzed in detail the difficulties associated with the application of numerical methods to Hallén's integral equation with the approximate kernel for the case of a lossless surrounding medium. This letter extends to the case where the medium is conducting and points out similarities and differences between the two cases. Our main tool is an analytical/asymptotic study of the antenna of infinite length.
