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

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 the PEC using the __S__24 FDTD method, which is capable of directly computing the antenna far‐field patterns. Accuracy of the algorithm is demonstrated by comparing the antenna patterns with those calculated from the near‐to‐far field transformation and cavity model. © 2004 Wiley Periodicals, Inc.

## Abstract In this paper, a novel preconditioner scheme slot neighbour (__SN__) preconditioner is applied to dense matrix equations derived from integral equations for a slot‐array antenna in order to improve the convergence of iterative integral‐equation solvers, such as the conjugate‐gradient (_
Given the remarkable advances in supercomputers, large-scale electromagneticfield analyses are becoming possible by FDTD parallel computation. In this study, a versatile FDTD parallel computation system is developed by using Fortran90 and the MPI library. The system uses dynamic memory allocation, w
This paper describes two strategies for the accurate computations of polential derivalives in boundary element methods. The first method regularizes the quasi singularity in a fundamental solution by referring the potential and its derivatives at the boundary point nearest to a calculation point in
