Abstract	A new improved PML called as uniaxial-pseudo propagation PML (UPP-PML) was proposed for the purpose to reduce computational costs from the conventional Berenger’s PML (B-PML). The UPP-PML is a new absorbing boundary condition for finite difference time-domain (FDTD) method. In our past study, propagation and absorbing ability without scattering object were investigated for the UPP-PML. In this study, we applied the UPP-PML to the FDTD method in scattering analysis. The scattering analysis for homogeneous sphere model with plane wave injection was evaluated as a case study. The distributions of effective value for electric field in the stationary state were evaluated. The numerical results with the UPP-PML were compared with those of exact solution and the conventional B-PML. It was found that the distributions of the effective value obtained with the UPP-PML were almost as same as those with the conventional B-PML result. Consequently, scattering analysis with the UPP-PML had almost as same calculation accuracy as the B-PML. Furthermore, using the UPP-PML made advantage in reduced computational costs over the BPML.
