Abstract

In this paper we present a technique for achieving high resolution in the FDTD. The technique combines model order reduction with subgridding. Such a combination allows one to condense mesh locally and get accurate results using limited number of variables. Moreover the overall time discretization step is longer than in case of the subgridding only. This enables one to perform the simulation quicker than in other schemes where fine mesh is used. The methodology of FDTD-macromodel scheme is demonstrated using a numerical example
