Optimum design of modern ground-satellite communication systems requires the knowledge of rain-induced differential attenuation, differential phase shift, and cross-polarization factors. After a comprehensive assessment of different available analytical techniques, an efficient technique is chosen to yield the desired scattering results. Tabulation of the scattered fields for Pruppacher-Pitter raindrops with sizes ranging from 0.25 mm to 3.5 mm at 20°C and at 30 GHz for several incidence angles is given.
