Popis: Material inhomogeneities are taken into account in the standard finite-difference time domain method by staircase modeling of medium boundaries. Resolution is, therefore, limited by Yee's cell sizes. In this paper, a new scheme is proposed, which improves material resolution without increasing the demand of computer resources.
