Propagation through a precipitation medium: Theory and measurement

The theory of propagation through a precipitation medium is based here on the differential propagation constant and two additional complex constants. The latter reduce to a single real parameter, the "canting angle," for certain simple models, for example, for a population of equioriented symmetrical scatterers. In a uniform medium the constants are closely related to the elements of an equivalent permittivity tensor. It is shown that the parameters can be determined from a sequence of depolarization measurements.
