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 It is well known that the numerical dispersion relations of all kinds of finite‐difference time‐domain (FDTD) methods, including the conventional FDTD and alternating‐direction implicit (ADI) FDTD methods, are derived from the assumption of plane wave. In the past, however, disregarding
## Abstract We present a parallel implementation of the three‐dimensional alternating direction implicit finite‐difference time‐domain (ADI‐FDTD) method in Cartesian coordinates using the message passing interface (MPI) library. Parallel implementations not only speed up computations but also incre
## Abstract The relationship of the numerical dispersion relation presented in different mathematical expressions (that are independently derived in 1, 2) for the three‐dimensional alternating direction implicit finite‐difference time‐domain (3D ADI‐FDTD) method is investigated. It is found that, u
## 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
