Modeling rain polarization effects to millimeter wave frequencies

The attenuation of a received signal on a millimeter wave (above 30 GHz) link probably will be considerably more sensitive to transmitted polarization of the signal then is the case on a microwave (below 30 GHz) link. The introduction of this report gives some background on past theoretical developments in assessing rain polarization effects. Then, a model is developed to more readily assess the rain attenuation polarization dependency, and this new model is compared with an accepted theoretical model. It is concluded, based on three separate sets of comparisons, that the model gives results close enough to the theoretical model to warrant consideration for its future use.
