Abstract

A novel Simple Anisotropic Effective Medium method (SAEM) based on local correction is presented in this paper by taking into account the physical effects of the partial material fulfillment on the permittivity and permeability of the distorted cells. It reduces the staircasing errors significantly and introduces physical insight, which proves to be efficient and straightforward to implement. The comparison between the numeric results and analytic solutions shows great improvement over the previous curved object modeling techniques.
