摘要:

控制和收集太阳辐射压力是一个重大挑战,然而,目前很少有潜在的解决方案适用于几个关键应用。在本研究中,设计了一种用于可见光谱的电可调等离激元超表面。此外,计算了作用在超表面上的法向和切向光学力。在异常反射中表现出高效率的同时,所设计的有源超表面提供了作用在其上的光学力的可调性。该超表面由嵌入在石墨烯层顶部的锥形银单元组成,石墨烯层有20层石墨烯片。因此,通过调节石墨烯片的费米能级,可以控制传递给超表面的动量。我们的结果可以为可调辐射压力收集、微型车辆、太阳帆和光镊中所期望的光学力控制提供一个合适的平台。

英文摘要:

Controlling and harvesting solar radiation pressure is a significant challenge, however, there are few potential solutions, which are suitable for several key applications. In this study, an electrically tunable plasmonic metasurface is designed for the visible spectrum. Moreover, the normal and the tangential optical forces acting on the metasurface are calculated. Whilst presenting high efficiency in the anomalous reflection, the designed active metasurface provides tunability of optical forces acting on the metasurface. The metasurface is composed of tapered silver cells embedded on top of the graphene layer with 20 layers of graphene sheets. Hence, by tuning the Fermi level of graphene sheets, the transferred momentum to the metasurface can be controlled. Our results can provide a suitable platform for optical force control desired in tunable radiation pressure harvesting, micro vehicles, solar sailing and optical tweezers.
