Analysis of Shielding Characteristics on the Cylindrical Lossy Multilayered Dielectric

In this paper, the shielding characteristics of a cylindrical multilayered dielectric are analyzed. In order to evaluate shielding effects, we consider the case that plane waves are incident upon an infinitely long cylindrical multilayered dielectric which surrounds a conductor core. For perfect and lossy dielectric distributions, total induced currents at the conductor surface are computed. It was found from those results that electromagnetic characteristics of the multilayered dielectric are largely dependent on dielectric distribution.
