Simulation of transient propagation through chiral metamaterials using a novel dispersive FDTD formulation

Abstract

A novel FDTD technique to model dispersive chiral media with Lorentzian electric and magnetic properties is demonstrated. This technique is based on the implementation of wavefield decomposition along with the piece-wise linear recursive formulation. Propagation of electromagnetic fields through a chiral slab will be calculated with the new formulations and validated through comparisons with known analytical solutions. The methodology introduced and discussed within this paper will provide the foundation to develop useful design tools for numerous EMC applications, including effective shielding mechanisms and improved antenna designs. This formulation is the first of its kind in the FDTD community
