| Abstract: | This paper discusses the Finite-Difference Time-Domain method with numerical examples.The scattering field of an infinite metal cylinder illuminated by Gaussian-pulse plane wave has been calculated.Comparing with the known results,it proves that the computer programmes in this paper are valid.With these programmes,the computed results for a dielectric cylinder in the lossy medium are presented. |
