Analysis of Electromagnetic Propagation for Evaluating the Dimensions of a Large Lossy Medium

In this paper the propagation of a plane wave in a large l ossy medium is presented. The investigated geometry consists in a wedge- shaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar technique for measuring the length of the dielectric wedge. In order to address this problem and to evaluate the radar echo signal, both the transient and harmonic analysis are performed.
