Abstract

A novel and robust numerical scheme was developed to model bi-isotropic materials in the time domain, based on the FDTD method. The main advantage of this new scheme is its inherent simplicity, which will easily allow the modeling of dispersive bi-isotropic behavior and of bi-anisotropic materials in the FDTD. Previous attempts have been made in the area of modeling chiral or bi-isotropic media. This paper details the main ideas behind a newly-developed scheme to model bi-isotropic materials using the FDTD technique and shows the results that validate the method.
