摘要

我们研究了表面等离子激元极化子(SPPs)在由周期性堆叠的石墨烯片阵列(GSA)中的传播。由于强耦合，SPPs在gsa中呈线性衍射关系。这种独特的特性有助于抑制SPPs在传播过程中的衍射。通过连接两个不同周期的gsa，可以在异质界面中产生spp的负折射。此外，我们还演示了非周期gsa中的加速和减速光束，从而导致波束路由效应。

Plasmonic beam control in strongly coupled graphene sheet arrays

We investigate the propagation of surface plasmon polaritons (SPPs) in the graphene sheet arrays (GSA) consisting of periodically stacking graphene sheets. Thanks to the strong coupling, SPPs experience a linear diffraction relation in the GSAs. The unique feature is helpful in restrain diffraction of SPPs during propagation. By connecting two GSAs with different periods, negative refraction of SPPs in the heterointerface may occur. In addition, we demonstrate accelerated and decelerated beams in aperiodic GSAs, resulting in the beam routing effect.
