| Abstract: | Absorbing performance of the perfectly matched layers is considered and an effective boundary condition for truncation of the perfectly matched layers is proposed in this paper The influence of different conductivity profiles and boundary conditions on absorbing performance of the perfectly matched layers is analyzed and the optimal perfectly matched layers are presented in the sense of minimum reflection |
| |
| Keywords: | finite difference time domain method(FDTD) perfectly matched layers(PML) boundary condition conductivity profile |
