Simulation of the Finite Difference Time Domain in Two Dimension

The finite-difference time-domain (FDTD) method is one of the most widely used computational methods i n electromagnetic. This paper describes the design o f two-dimensional (2D) FDTD simulation software for transverse magnet ic (TM) polarization using Berenger's split-field perfectly matched layer (PML) formulation. The software is developed using Matlab programming language. Numerical examples validate t he software. Keywords—Finite difference time domain (FDTD) method, perfectly matched layer (PML), split-filed formulat ion, transverse magnetic (TM) polarization.
