Thin-Wire Methods for Electromagnetic Problems Involving Advanced Composite Materials.

Abstract

This report describes loaded thin-wire models for the representation of the electromagnetic properties of advanced composite materials. Techniques are described for the treatment of thin-wire antennas over advanced composite surfaces and for back-scattering from composites. Special techniques are required for the representation of attachment points. Skin effect is taken into account. Antenna efficiency and gain are computed. The results indicate that a small metal 'pad' at attachment points may significantly improve efficiency. Far field beam patterns may remain essentially unchanged as efficiency or backscatter varies over a wide range. (Author)
