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: 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

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
