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.

$SParameterDirectory

$TimeStep

$OutputStep

$SpaceRegion

$CellNumber

$BCsetting

$PMLlayer

$SourceType

$SourcePosition

$SourceFrequency

$NumberofObject

$MaterialStructure

$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.

$SaveType

$CourantFactor

$Backgroundparameter

$CPML_m

$CPML_max_kapa

$CPML_ma

$CPML_max_a

$CPML_ratio_maxsigma
