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 Verifying the duality of electric and magnetic fields using the nonstandard FDTD method is important for far‐field calculations using the equivalence principle and for the reduction of reflection from boundaries of different size lattices. In this paper, the duality of the fields using
## 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
