Millimeter Wave Propagation Through Layers of Sand and Dust Particles Mukesh Kumar

In the present paper theoretical investigation has been carried out to evaluate the effect of the layers of sand, dust particles on the propagation of millimeter wave. For this purpose the layers of sand, silt and clay particles have been considered. The expression for effective propagation constant has been utilized to get the expression for the normalized phase velocity, loss tangent and related attenuation. It has been found that the normalized phase velocity, loss tangent and attenuation, all increase with increasing frequency for different values of fractional volume.Further the loss tangent first increases with increasing fractional volume and then it starts to decrease with increasing fractional volume. .
