Scattering of electromagnetic waves by a chiral object of ellipsoidal shape

The potential applications of electromagnetic (EM) chirality, together with the fact that a general ellipsoid shape can simulate a variety of common o bjects, such as discs, needles etc., constitute the motivation of the prese nt work. Scattering of EM waves incident on an ellipsoidal object of chiral property is analyzed using Fourier analysis, in conjunction with an integr al equation technique. The inner field of the scatterer is described in ter ms of superposition of plane waves satisfying the vector Helmholtz wave equ ation inside the chiral media and a Galerkin procedure is employed to solve a volume integral equation obtained by applying the Green's theorem. A hig hly stable numerical code is obtained, which is verified by comparison with previously published solutions. Numerical computations have been carried o ut for various scatterers and interesting scattering properties of waves fr om chiral media are observed. Especially for a linearly polarized plane wav e incidence, the subsequent change of its polarization is investigated and discussed.
