A Three-Dimensional Fourth-Order ADI-FDTD Method and Its Application in Cavity Problems

Attention was focused on the three-dimensional fourth-order alternating-direction implicit finite-difference time-domain (3D 4th-order ADI-FDTD) method using the 4th-order spatial difference and the 2nd-order temporal difference. Firstly, the numerical formulation of the 4th-order ADI-FDTD method is presented. Secondly, the numerical dispersion relation is… CONTINUE READING
