Analysis of Simplified SB-ADI Scheme for Two-Dimensional Maxwell's Equations

This letter represents a simplified sampling biorthogonal alternating-direction implicit (SSB-ADI) method based on the sampling biorthogonal time domain (SBTD) algorithm. Two sampling functions with different orders for sampling biorthogonal method are used to display spatial discretization. Dispersion and stability analyses are presented. It is shown through a numerical simulation that SSB-ADI reduced the CPU time and memory compared to the SB-ADI method.
