I want to simulate random media filled with discrete scatterers with an appropriate numerical method.
is it possible to calculate the scattering with S-FDTD or (ordinary )FDTD method? if not what would you recommand to better describe the wave propagation behavior in such medium?
thanks
I think there are at least two ways to do this. First, the brute force method is to setup a large enough grid to fit a large enough random distribution of rain drops to get meaningful data. Second, you can look into effective medium models for rain. If you have some idea on the statistics of the rain drops such as size, spacing, etc., you could calculate the effective permittivity and then simulate transmission through a homogeneous medium with the permittivity set to the effective permittivity of the rain. I suspect of you do a literature search, you will turn up lots of things for effective properties of rain. It seems like that would be a common need.
Thank you Mr.javadinasab for your useful suggestion. could i use CST instead of Lumerical software for the mentioned medium?
thanks a lot prof.Rumpf for your realy useful suggestion, surely i will do some literature search to find out more infomations and datas to better define and model the medium.
