采用二阶、四阶和六阶精度部分算子的求和方法，模拟了电磁波在材料不连续点附近的传播。不连续处的界面条件采用同时逼近项法。表明了该方法的稳定性，并对其精度进行了数值验证。
Electromagnetic wave propagation close to a material discontinuity is simulated by using summation by part operators of second, fourth and sixth order accuracy. The interface conditions at the discontinuity are imposed by the simultaneous approximation term procedure. Stability is shown and the order of accuracy is verified numerically.
