Abstract

In this paper, electromagnetic wave propagation close to a material discontinuity has been simulated. We have used summation by part (SBP) operators of second, fourth and sixth order accuracy. The boundary conditions have been imposed by the simultaneous approximation term (SAT) procedure. Stability has been shown and the order of accuracy has been verified numerically.
