A perfectly matched layer (PML) medium with complex frequency-shifted (CFS) constitutive parameters is introduced for the multiresolution time-domain (MRTD) method. The absorbing boundary is implemented by using the convolution PML (CPML), which is easier to obtain and more memory saving than the conventional implementation of PML when treating more generalized media. Numerical results show that the...
In this letter, the complex frequency-shifted perfectly matched layer (CPML) is applied to hybrid implicit-explicit finite-difference time-domain method (HIE-FDTD). To verify the new formulation, a numerical example is presented. Results show that both HIE-CPML and FDTD-CPML have almost the same reflection error, while their reflection error is smaller than HIE Mur's first-order results. Results for...
