通过扩展频域（FD）渐近解（FD-ASs），我们简要地提出了高频脉冲波入射到二维涂层圆柱上时瞬态散射电场的时域（TD）渐近数值解（TD-ANSs）。我们假设涂层介质与入射脉冲波的中心角频率的波长相比是厚的。与常规TD-ANS相比，TD-ANS包括穿过涂层内部的多重反射效应。通过与参比溶液的比较，证实了TD-ANS的有效性。
By extending frequency-domain (FD) asymptotic solutions (FD-ASs), we briefly propose time-domain (TD) asymptotic-numerical solutions (TD-ANSs) for a transient scattered electric field when a high-frequency pulse wave is incident on a two-dimensional coated cylinder. We assume that a coating medium is thick as compared with the wavelength of a central angular frequency of an incident pulse wave. The TD-ANSs include multiple reflection effect passing through an inner portion of the coating layer as compared with a conventional TD-ANS. The validity of the TD-ANSs is confirmed by comparing with a reference solution.
