Abstract

In this paper, a finite element (FEM) investigation of composite materials is studied. A pemittivity profile of the material is implemented to correspond to the Packing fraction of the physical composite. Curve fitting is applied to the standing wave pattern to determine the effective attenuation coefficient and propagation constant in the composite. The complex permittivity as a function of packing density is then determined. A comparison between the two dimensional and three dimensional measurement simulations is presented. An adaptive scheme is implemented to improve resolution of the finite element particulates.
