Abstract

We discover deep-subwavelength, low-loss, and diffraction-free surface plasmon polariton (SPP) beam routing effects in aperiodic graphene sheet arrays (a-GSAs). The a-GSAs are constructed by varying either the interlayer spaces between graphene or the individual graphene chemical potentials. The SPP beams can be accelerated or decelerated in the a-GSAs, resulting in beam routing in different paths. The wave fronts of the beams are always parallel to the propagation direction, allowing the generation of transverse radiation pressure. All of these behaviors of SPPs are demonstrated by fully vectorial simulation and Hamilton optics analysis.
