  • Abstract
    This short paper introduces a novel approach to improve the accuracy of the surface impedance boundary condition (SIBC) model originally reported by Celuch. The accuracy of the SIBC algorithm is significantly improved by introducing time and/or space synchronizations but still maintains a simple time update equation. Examples demonstrate the effectiveness of the approach. In addition, a ladder element optimization algorithm is introduced to account for the finiteness of the GC-ladder.
