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 ==
<font size=3 color=red>'''Be careful:'''</font> 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:''' Without the input file 2, you can still run the FDTD program. However, if using this, you have to really realize the meaning of each function and parameter; otherwise, you should not change the default parameters in each function.
