Abstract:

A novel implementation of shift operator to complex frequency shifted perfectly matched layer (CFS-PML) is presented for the truncation of finite-difference time-domain lattices. The CFS-PML formulation based on stretched coordinate Maxwell curl equations is deduced and combined with the shifted operator method, which is referred to as SO-PML that is completely independent of the host medium and may be applied to general medium. Computation examples demonstrate its efficiency and feasibility. In addition, the proposed SO-PML is easily understood in concept and implemented in programming.
