3D-FDTD is named from three dimensional finite difference time domain method. This program models computational electrodynamics which is refer to the book Computational Electrodynamics: The Finite-Difference Time-Domain Method, Third Edition, by Allen Taflove.


Input file 1: parameters assigned command

Be careful: Although most sequences of functions are not important, the function $NumberofObject MUST appear before the function $MaterialStructure and $MaterialParameter.

Input file 2: parameters assigned command

Note: You can run the FDTD program WITHOUT the input file 2. However, if using this, you should really know the meaning of each function and parameter; otherwise, the program may not execute correctly as you change any default parameter.
