A Three-Dimensional Finite-Difference Time-Domain Scheme Based on a Transversely Extended-Curl Operator

Abstract

In this paper, a three-dimensional finite-difference time-domain (FDTD) scheme is presented with improved isotropy characteristics and higher Courant number than the standard Yee scheme. The basic idea is to transversely extend the curl operator in order to improve the transverse Laplacian representation of the curl-curl operator. A stability analysis is… (More)
