| Abstract: | In this paper, the scattering characteristic of the tree is analyzed by using FDTD method. In order to deal with electromagnetic interaction of ground and tree, the incident field and the reflecting field of ground are treated as two excitated sources of the tree. The scattering fields of tree-teuck in frequency domain, time domain, polarization domain and space domain are simulated and discussed, respectively. |
