The analysis of radiation and scattering from thin wire structures using the integral equation approach is a very important topic in antenna theory and also in many areas of electromagnetic compatability (EMC). Written in the form of a research report, this book aims to explain the theoretical background of the wire antenna analysis in both the frequency and time domain, and covers many important topics regarding wire antennas and related EMC topics. It also introduces the reader to the Finite Element Integral Equation Method (FEIEM) developed by the author.
