Abstract: Theoretical investigation has been carried out to evaluate the depolarization of millimeter wave from the layers of three main constituents (sand, silt and clay) of storm. Both ellipsoidal and spheroidal (prolate and oblate) shape of dust particles are considered. The concept of differential phase and differential attenuation has been utilized to quantify the depolarization. It has been found that, in general, differential attenuation, depolarization angle depolarization and loss due to depolarization produced by ellipsoidal dust particles are higher than those produced by the spheroidal dust particles. The prolate spheroidal dust particles are found to cause more depolarization and attenuation as compared to those by oblate spheroidal dust particles. It has also been observed that the depolarization and loss due to depolarization caused by ellipsoidal and spheroidal dust particles depend directly on frequency and particle density.
