Abstract

This article deals with the analysis of electromagnetic wave scattering by a chiral cylinder in free space. Techniques for the numerical electromagnetic analysis of biisotropic media based on the finite difference time domain method have been previously proposed and investigated. One of these techniques, called BI-FDTD, is used in this paper to compute the scattered field. The distinctive feature of the technique is the use of two independent sets of wavefields representing the left- and right-polarized waves in the chiral medium. The simulation results are compared with the analytical solutions for the circular cylinder derived using the plane wave decomposition into spherical harmonics.
