Abstract
Material inhomogeneities are taken into account in the standard finite-diff erence time-domain method by staircase modeling of medium boundaries. Resol ution is, therefore, limited by Yee's cell sizes. In this paper, a new sche me is proposed, which improves material resolution without increasing the d emand of computer resources.
