A novel dispersion formulation of the 2D alternating-direction implicit (ADI) finite-difference time-domain (FDTD) method is presented. The formulation is based on an increasing process analysis of the monochromatic wave in free space. A numerical experiment scheme is designed to verify the accuracy
## Abstract In this article, an accurate numerical dispersion relationship is developed for 3‐D alternating direction implicit finite difference time domain (ADI FDTD) with artificial anisotropy. The numerical dispersion relation with accurate mathematical model helps to calculate the anisotropic p
## Abstract We propose a new adaptive alternating‐direction implicit finite‐difference time‐domain (ADI‐FDTD) to reduce the anisotropy in the numerical phase velocities. The proposed form has two anisotropic parameters on the first order terms of the time step and one parameter on the second order
## Abstract We introduce a new, alternative form of the 3‐D alternating direction implicit finite‐difference time‐domain (ADI‐FDTD) algorithm that has a number of attractive properties for electromagnetic simulation. We obtain a leapfrog form of the time‐advance equations, where the E and H fields
