earthSurfacePermittivity
Permittivity and conductivity of earth surface materials
Syntax
Description
The earthSurfacePermittivity
function computes electrical characteristics
(relative permittivity, conductivity, and complex relative permittivity) of earth surface
materials based on the methods and equations presented in ITU-R P.527 [1]. The
earthSurfacePermittivity
function provides various syntaxes to account for
characteristics germane to the specified surface material.
