Computation of coherent electromagnetic wave propagation through rain medium with a realistic raindrop shape is the subject of this work. T-Matrix approach towards the computation of forward scattering amplitude of raindrops is considered numerically exact. The results of Total Cross Section and forward scattering amplitude due to raindrops with MPP model shape are calculated by T-Matrix method. Both horizontal and vertical polarization of incident wave are considered where specific attenuation, phase shift and cross polarization discrimination (XPD) for terrestrial coherent electromagnetic wave propagation in the frequency range of 3-300 GHz are presented. Furthermore the effect of temperature on specific attenuation vs. frequency is investigated.
