| Abstract: | The time domain finite-difference(FDTO)method has already been applied to many areas of electromagnetic scattering, radiating and inverse scattering.Absorbing boundary condition plays a critial role in FDTD.In the paper, authors apply an effectlve transmitting boundary condition to improve the results of FDTD,and present two new methods,losa layers method and superabsorption method,to improve the transmitting boundary Condition. |
