Abstract

In this paper, we present a new semi-analytic formulation for analyzing the electromagnetic field propagation along a metallic cylindrical rod immersed in a biaxially anisotropic and lossy media. This geometry can be employed for investigating the propagation around a circular well with important engineering applications for the oil and gas industry. The excitation of surface waves is explored herein by using current loop sources via a spectral domain approach where a novel Hankel-based integral transform is introduced. We present a series of validation results which show that our technique is numerically stable and robust for modeling several representative problems.
