The effects on pair correlation function of coherent wave attenuation in discrete random media
Abstract
The Percus-Yevick approximation (P-YA) of pair correlation function for hard spheres is combined with the T-matrix formulation to study the coherent wave attentuation of electromagnetic wave propagation in a discrete random medium. The effect of the pair correlation function is seen to be significant at high fractional volumes of the discrete scatterers (equal to or greater than 0.125), but also depends on the frequency of the propagating wave - the effect being less at higher frequencies. The results are compared with previous calculations which employed the 'well-stirred approximation' (WSA) for the pair correlation.
