The ray-series (RS) method, which is practically more tractable and feasible than the transfer matrix (TM) method for the time-domain analysis, is examined and applied for investigation of temporal reflection and transmission responses of an $N$ -layer structure for a plane wave incidence. These responses are represented by reduced reflection and transmission coefficients associated with unit step functions with different effective time periods and weightings depending on electromagnetic properties of the layers constituting the $N$ -layer structure. Numerical and simulation analyses in line with the residue theorem and Bromwich integral were performed to validate our formalism and practically demonstrate its applicability for temporal analysis.

用射线系列方法测定 N 层结构内平面波的时间特性

射线序列 (RS) 方法实际上比用于时域分析的传递矩阵 (TM) 方法更易于处理和可行，并被用于研究物体的时间反射和传输响应。 $N$ - 平面波入射的层结构。这些响应由与具有不同有效时间段和权重的单位阶跃函数相关联的减小的反射和透射系数表示，取决于构成层的电磁特性 $N$ -层结构。进行了符合残差定理和布罗姆维奇积分的数值和模拟分析，以验证我们的形式主义并实际证明其适用于时间分析。
