The Computed Results for the Scattering Field of a Dielectric Cylinder in the Lossy Medium with FD-TD Algorithm |
| |
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. |
