Rain attenuation calculation using dielectric mixture with deformed rain drops

A modified approach in computing the effective permittivity of a dielectric mixture, which takes into account the distributions in rain drop sizes, shapes and depolarization factors, has been used to obtain the rain-attenuation of both the horizontally and vertically polarized wave. The computed results agree well with those obtained from the more complicated Mie scattering theory. The differential attenuation of a horizontally and vertically polarized wave is obtained using the proposed model and compared favorably with Oguchi´s result for the cases of rain droplets in the form of oblate spheroids and in a form described by Pruppacher and Pitter
