Electric Field Detection

A fortran sample code which in Finite Difference Time Domain Method for Electromagnetics. - Kunz K.S., Luebbers R.J. book was translated to matlab code. For movie, a little bit code must be added into it. Especially it needs to vectorize for electric field updates.

Implementation of Fast Fourier Transform based Homogenization for heterogeneous materials dealing with electric or heat conductiviy. It takes the values of conductivity at regular grid of periodic unit cell that represents the material and produces the distribution of local fields such as...
