Modelling characteristics using FDTD
I am modelling the effect of soil heaps on radio signals (Think radio communication between mine dumps.) and would like to know what permittivity, permeability and electrical conductivity values one should use in the FDTD. I am currently making some loose assumptions on conductivity from a Geophysical book by Telford. What to do about the permittivity and permeability values?
I note in some of the literature that soil is defined as a dielectric and that permittivity is complex . Is this really necessary ? Could one only use the static permittivity for soil ? Not much description of permeability effects, although I imagine that this will be handled in same way as permittivity.
