Perfect matching layer for Haar wavelet based Multi-Resolution Time-Domain technique

The multi-resolution time-domain (MRTD) technique is a superior numerical algorithm over the long established finite difference time-domain (FDTD) technique. The advantages of low numerical dispersion and less memory intensive are particularly of interest for analyzing hybrid structures involving antennas and metamaterials. In this paper, the Haar wavelet based MRTD is reviewed. A precise formulation of the intrinsic perfect matching layer (PML) boundary condition in level one Haar MRTD is presented for the first time, which can be further expanded to any level of the Haar wavelet basis functions.
