Abstract

This paper investigates the effective energy reflectance of materials comprised of a continuous matrix embedded with fine-scale particles of different electric permittivity and magnetic permeability. The specific objective is to determine under what conditions will increasing the particulate volume fraction initially increase (or decrease) the overall reflectance from a pure-matrix base state and, with further increase in volume fraction, reverse the trend, i.e. decrease (or increase) the effective reflectance. The importance of this condition is that it indicates when the correlation of a specific level of reflectance to a specific volume fraction of particles may not be unique, even when the properties of the particles and matrix are fixed.
