Abstract :
In this work we demonstrate experimentally the manipulation of Airy surface plasmon beams in a linear potential system. We used a negative-tone grey-scale electron beam lithography to fabricate plasmonic structures with a dielectric ramp which provides a graded refractive index. Using such carefully engineered structures we show that the bending of an Airy surface plasmon beam can be fully reversed and controlled by the potential.
