In order to analyze the time-domain characteristics of multilayered lossy medium, a novel theoretical solution for calculating the transient reflected wave from the multilayered lossy medium is presented. We obtain the formulas of the time-domain interfacial reflected coefficient of the interface that separates two lossy media for the transverse electric (TE) and transverse magnetic (TM) modes according to the time-domain propagating mode method. The cases of three-layered lossy medium are illustrated to verify the accuracy and validity of the proposed method. Numerical results confirm that the proposed method is quick and valid to deal with the transient reflected wave from a multilayered lossy medium.

多层有损介质中脉冲平面波的时域反射

为了分析多层有损介质的时域特性，提出了一种计算多层有损介质瞬态反射波的理论方法。我们根据时域传播模式方法，获得了将两种有损耗介质分离为横向电（TE）和横向磁（TM）模式的界面的时域界面反射系数的公式。以三层有损介质为例，验证了所提方法的准确性和有效性。数值结果表明，该方法能够快速有效地处理来自多层有损介质的瞬态反射波。
