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 This paper deals with spatial and time refinement using the FDTD‐3D method. An original methodology is presented in which time refinement and spatial refinement with a ratio of two are performed in two separated stage. It aims to simplify algorithms of refinement schemes and to better c
## Abstract The numerical dispersion of a proposed new FDTD scheme is often evaluated and compared with that of well‐established FDTD methods. Because there may be a theoretical deficiency in the dispersion analysis, numerical experimentation is often used to validate the dispersion relation. This
The hybrid FDTD᎐FETD method de¨eloped by Wu and Itoh is extended to handle dispersi¨e materials using a finite-element ¨ersion of the recursi¨e con¨olution method. For scattering by a plasma sphere with negati¨e real permitti¨ity, the hybrid FDTD᎐FETD method is found to be more accurate than FDTD, e
The frequency dependence of the characteristic impedance of microstrip lines has been in¨estigated by many authors using 3D-FDTD formulations. In the present letter, a two-dimensional FDTD scheme is used to calculate both the propagation constant and the characteristic impedance of the fundamental q
