The simulation results show that the absorbing effect of the proposed boundary is good, and the model has higher computing accuracy and cost less time to achieve convergence compared to the finite-difference time-domain (FDTD) algorithm. Compared with the perfectly matched layer (PML), the proposed boundary can reduce the computing cost largely, especially for high order MRTD calculation. Meanwhile, we propose a new absorbing boundary named the FDTD/PML connection absorbing boundary condition to simplify the field calculation at the boundary area.
Abstract We derive the TE-mode two-dimensional multi-resolution time-domain (MRTD) iterative equations based on compactly supported wavelet basis functions as Haar, Daubechies and Coifman, and we develop a basis function selectable electromagnetic scattering forward model according to the derived equations.
