Abstract

Based on the forward scattering amplitude function for charged sand particles under the Rayleigh approximation and the effective permittivity method a calculation model for microwave attenuation due to charged sand particles is given in terms of equal sized distribution and lognormal size distribution and the attenuation is calculated and analyzed The results show that the attenuation with charged sand is greater than the case of no charge and the more concentrative the surface charges on sand particles are the greater are the influences on microwave attenuation When the frequency is not too high natural sand and vehicular sand have little effect on microwave attenuation whereas the attenuation of explosive sand need be considered
