One dimensional (1D) simulations are carried out using Matlab and for two dimensional (2D), MTM-FDTD Virtual Tool is used. In particular, a stable finite difference approximation to the one-way wave equation is also required (cf. FDTD is a computational technique for solving electromagnetic wave equations.

Implementation of the finite difference time domain method Kroll L09 19. In this context, the two-dimensional finite- difference time-domain (2D-FDTD) method is used to simulate the surface Plasmons (SPs), with the perfectly matched layer (PML). FEMur (The Finite Element Method Universal Resource) was developed both as an introduction to the finite element method and as a compendium of the finite element method.
