| Abstract: | We present a method for electromagnetic scattering with obliquely incident pulse plane wave using BOR-FDTD(body of revolution finite-difference time-domain) method.The obliquely incident pulse plane wave is expanded in a cylindrical coordinate and a total-field/scattered-field formulation is introduced as excitation.The method is validated by comparing with the method of moments.It shows good agreement. |
| Keywords: | body of revolution finite-difference time-domain(FDTD) obliquely incident |
