抄録(英) | Application of finite difference time domain (FDTD) method in Ground Penetrating Radar (GPR) simulation, the absorbing boundary is one of key factors to improve the calculation accuracy. The classical PML boundary condition would make spurious reflection for the waves being incident on the PML interface at near-grazing angles, low frequency waves, or evanescent waves. The non-split complex frequency-shifted PML absorbing boundary which based on recursive integration (CFS-RIPML) has a good absorption effect on these interference waves. In addition, it could be directly applied in the isotropic, anisotropic, dispersion or the nonlinear medium. In this paper, we derived the three dimension CFS-RIPML absorbing boundary formula and realized it. The numerical simulation shows that the CFS-RIPML is significantly better than UPML and PML boundary in absorption effect, calculation accuracy, reflection error. |
