摘要

在过去的几年里,时间超材料已经被利用作为一个新的平台来构思几种基于异常散射响应的电磁和光学器件,这些器件是在其介质性质的一次或多次突然变化中实现的,然而在现实情况下很难实现。在这封信中,我们研究了在不作用于介质性质的情况下模拟时间超材料散射响应的可能性。但在有效折射率和波阻抗感知的波传播期间,在一个指导结构,而不是实际的材料,通过作用于其边界。该工作以封闭形式给出了当边界性质突然改变以诱导有效时间界面时所获得的散射系数。在这个框架中,时间控制的元表面可以用来实现所提出的概念,为微波和光学频率下的新器件的设计和实现提供了更容易的途径。

Temporal interfaces and metamaterial response enabled by boundaries
In the last years, temporal metamaterials have been exploited as a novel platform for conceiving several electromagnetic and optical devices based on the anomalous scattering response achieved at a single or multiple sudden change of their medium properties, which however is difficult to carry out in a realistic scenario In this letter we investigate on the possibility to emulate the scattering response of a temporal metamaterial without acting on the medium properties, but on the effective refractive index and wave impedance perceived by the wave during the propagation within a guiding structure rather than the actual material, by acting on its boundaries. The work presents in closed form the scattering coefficients achieved when the boundary properties are suddenly modified for inducing an effective temporal interface. In this framework, temporally controlled metasurfaces can be used to implement the proposed concept, giving an easier path also to the design and realization of novel devices at microwave and optical frequencies.
