Alternating-direction explicit FDTD method for three-dimensional full-wave simulation

Open publisher page 9 citations

Abstract

In this paper, we propose a new FDTD (Finite-Difference Time-Domain) method using the alternating-direction explicit (ADE) method for the efficient electromagnetic field simulation. This method is based on the ADE method which has been used as the explicit-type finite-difference algorithm for solving diffusion equations. Our approach is the first application of the ADE method to the 3D-FDTD method. Furthermore, we introduce an absorbing boundary condition suitable for the 3D ADE-FDTD method which has been modified from the PML (perfectly matched layer). Finally, the efficiency of the ADE-FDTD method is evaluated by computer simulations.
