What is the advantage of the WIPL-D software over the FD-TD?
WIPL-D software is based on the MoM/SIE, and because of that it does not need any absorbing boundary conditions and discretization of the volume outside of the device under investigation. Accuracy of the FD-TD modeling is mostly related to the discretization quality and minimum one discretization point per tenth of the wavelength is recommended. This leads, in case of electrically large structures, to a very high number of discretization points and usually huge time of computation. If the actual result is wanted at one frequency or at selected number of frequencies, it may be expected that WIPL-D software may need an order of magnitude shorter computation time.
