Method of auxiliary sources for the analysis of insulated wire antennas

In this paper, a possibility of applying the method of auxiliary sources (MAS) in analyzing the characteristics of insulated wire antennas in layered media has been explored. The existing DGF-MAS technique for the analysis of bare antenna in layered media has been revisited and extended to analyze insulated antennas, which has been overlooked by other researchers. Numerical examples have been presented for several interaction problems to demonstrate validity, accuracy, and efficiency of the proposed technique. The proposed method can also be applied to the analysis of antennas immersed in arbitrary shaped insulation layer. Furthermore, analysis of the wire antenna with a spherically layered insulator which is eccentric to a spherically layered medium and more practical case of insulated antenna problem such as the wire antenna with a spherically layered insulator in a cylindrically layered medium, which models the wireless capsule endoscopy application roughly, is under investigation.
