摘要

在许多波传播应用中，同时提供多种操作的电磁结构是非常需要的。在这封信中，我们提出了可以实现多种功能而不需要任何动态元素的全金属metagrating。组成散射体是空间色散的（非局部的），并且被设计成这样，在一组指定的入射角下，横向磁（TM）极化激发会发生各种波变换。此外，所设计的结构完全反映了横向电（TE）极化下的入射功率。结果表明，利用这些结构可以同时实现许多反常的折射和反射现象。由于被动和静态，这种结构可以有效地用作各种设备，如光束偏转器，隔离器和偏振器。

Multifunctional Static Metagratings Using Metallic Scatterers With Strong Spatial Dispersion

Electromagnetic structures that provide multiple operations simultaneously are highly desired in several wave propagation applications. In this letter, we propose all-metallic metagratings that can realize multiple functionalities without requiring any dynamic elements. The constituent scatterers are spatially dispersive (nonlocal) and are designed such that, at a set of specified incident angles, various wave transformations occur for transverse magnetic (TM)-polarized excitations. Moreover, the designed structures completely reflect the incident power under transverse electric (TE) polarization. It is shown that, using these structures, many anomalous refraction and reflection phenomena can be achieved simultaneously. Being passive and static, such structures can be efficiently utilized as various devices like beam deflectors, isolators, and polarizers.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
