FDTD Method Simulation with Perfect Matching Layer at GSM Frequency

Abstract

The finite-difference time-domain (FDTD) method is one of the most widely used computational methods in electromagnetic. This paper study the simulation of wave propagation using one and two Finite Difference Time Domain method has been studied. It being used to study the time evolution behavior of electromagnetic field by solving the Maxwell's equation in time domain using perfect matching layer boundary condition. The basic idea is this that the amount of reflected waves is dictated by the intrinsic impedance of the two medium. The software is developed using Matlab programming language. Numerical examples validate the software. is more general since it includes both the propagating mode regime and the evanescent mode regime. Robert et al studied an adaptive finite element method for the wave scattering with transparent boundary [10]. Also viewpoint allows PMLs to be derived for inhomogeneous media such as waveguides, as well as for other coordinate systems and wave equations [11]. In this work we studied the simulation of global system mobile wave propagation using one and two Finite Difference Time Domain method. It being used to study the time evolution behavior of electromagnetic field by solving the Maxwell's equation in time domain using perfect matching layer boundary condition.
