✦ Synopsis

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¨en when a mesh size four times smaller is used in the latter method.

## Abstract Directly applying the higher‐order FDTD method to the computation of antenna patterns has not been a practical approach thus far. One of the main difficulties is how to handle the perfect electric conductor (PEC), which is always present. This paper describes a procedure for handling th

## 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
