Abstract

A test case of a chiral half-space was prepared using a dispersive finite difference time domain (FDTD) technique. The transmitted waveform of a Gaussian plane wave that was normally incident upon the interface of free space and a chiral medium was calculated and compared to its analytical solution. The electric and magnetic field values were plotted against their positions within the chiral halfspace. Slight disagreement between the peaks of the two curves possibly due to numerical dispersion errors was observed. It was found that in a chiral medium, both co- and cross- polarized waves were supported.
