3D FDTD code for electromagnetic simulation

代码说明：

In the pFDTD, pre-defined, a number of functions helps you to input complex dielectric/metallic structures by the repeated use of rather simple geometric structures. For example, the later use of input object functions will take over the overlapped region with the previously defined structures. In the present pFDTD version, only metals that can be described by simple Drude model can be handled.
