Abstract

Abstract

The problems for calculating EM energy absorption by lossy dielectric scatterer irradiated by plane wave are discussed. The factors effecting the accuracy of com-putation are discussed. The calculated resuhs of EM energy absorption and its distribution in homogeneous and layered homogeneous lossy dielectric spheres are presented, and the com-parison of these results with analytical soturion is given. The calculation is carried out for dielectric cylinder on conducting ground as well, and the result is compared with the image theory. All the computations show that the finite-difference time-domain method can give satisfactory results.
