The existence of a zero-crosspolarization mode through rain
Abstract
A zero-crosspolarization mode has been identified for the transmission of orthogonally polarized signals through rain; this finding may aid in implementing same-channel frequency reuse with dual orthogonal polarization in regions experiencing frequent heavy rainfalls. In a treatment using the canting angle of the raindrop as the random variable, zero-crosspolarized modes are shown to exist for both linear and circular polarizations. Application of the zero-crosspolarization mode to satellite communication systems is also considered, with particular attention given to effects due to an oblique transmission path, a wide coverage area and a change in the wind direction.
