Electromagnetic Properties and Effects of Advanced Composite Materials: Measurement and Modeling

Abstract

This report covers several areas: (1) Electromagnetic properties of composite materials are given for the range DC to 30 MHZ; (2) Techniques of measurement are discussed in the range DC to 1 GHz; (3) Electromagnetic shielding theory is discussed; Surface transfer impedance and the two loop method are related to the conductivity. A matrix method for the calculation of shielding effectiveness for laminated anisotropic materials (perpendicular incidence) is presented; (4) The modification required by the method of moments to allow calculation involving non-perfect conductors are discussed; and (5) A comparison of antenna patterns over a graphite/epoxy ground plane and an aluminum ground plane for dipole and monopole antennas at 370 MHz and 837 MHz is given.
