摘要

利用时间卷积型时域电磁互易定理，对具有时变磁介电特性的高对比度薄超表面的脉冲电磁平面波散射进行了解析分析。结果表明，(1+1)-时空散射问题可简化为两个可解析解的不耦合微分方程系统。在薄层中产生的结果场随后用于表示所需的散射场。讨论了相应的零反射条件。给出了数值算例，并进行了数值验证。

Transient Electromagnetic Plane Wave Scattering by a Time-Varying Metasurface: A Time-Domain Approach Based on Reciprocity

The pulsed electromagnetic (EM) plane-wave scattering by a thin, high-contrast metasurface with time-varying magneto-dielectric properties is analyzed analytically with the aid of the time-domain (TD) EM reciprocity theorem of the time-convolution type. It is shown that the (1+1)-spacetime scattering problem can be reduced to a system of two uncoupled differential equations that are amenable to analytical solution. The resulting fields induced in the thin layer are subsequently used to express the desired scattered fields. The pertaining zero-reflection condition is discussed. Illustrative numerical examples are presented and validated numerically.
