RCS Calculation #199

Hello, can this code calculate the radar cross section (RCS) of a metal sphere + dielectric layer model

zer011b commented 1 month ago

Currently only Drude model is supported. NTFF can be used to obtain far field from near field and then save it to output. Currently there's no built-in RCS calculation in fdtd3d, so external tools/scripts have to be used on previously calculated far field to transform it to RCS.
