PEC Condition Implementation for the Novel Weakly Conditionally Stable Finite-Difference Time-Domain Method

摘要

The perfect-electric-conductor (PEC) condition implementation for the novel weakly conditionally stable finite-difference time-domain (NWCS-FDTD) method is discussed in this paper. It shows that the method that the PEC condition is directly incorporated within the tri-diagonal matrix is more accurate and the burden on the computation efficiency is trivial. The theory proposed in this article is validated through numerical example.
