Treatment technology for dielectric media interfaces using multiresolution time-domain scheme

In the paper, we have discussed the distribution of the dielectric coefficients for the dielectric media interfaces, and have studied the solving methods of the permittivity in the multiresolution time-domain (MRTD) scheme. The MRTD results have been compared with those of analysis results and the FDTD method in an EBG structure and a half-filled cavity. It has been shown that the MRTD scheme with different basis functions is more accuracy and less computational memory than the traditional FDTD method.
