| Abstract: | Finite Difference Time Domain Method (FDTD) is a new numerical method in calculating electromagnetic scattering. This paper presents the thoughts of this method firstly, then the scattering field of a sphere is calculated with this method and the result is compared with the exact one obtained with MIE theory. The well agreement of these two results shows that FDTD method is effective. The issue that must be noted in the use of FDTD method is introduced. |
| Keywords: | FDTD electromagnetic scattering numerical simulation |
