Study of plane wave absorbing effectiveness of conductive polymer films

Abstract

A novel material, specifically, the conductive polymer PBT doped by ion-implantation with iodine, is studied to investigate its possible utilization as a microwave absorber. In the ion-implantation-doped polymer film, the dopant penetrates into only a layer situated close to the film surface. Hence the polymer film can be modeled as a two-dielectric layered medium, with the layer close to the surface corresponding to the doped polymer accompanied by a high conductivity, and the other layer corresponding to the undoped lossless polymer. Layered medium electromagnetic theory is applied to compute the overall reflection coefficient with a few numerical examples.<>
