Abstract :
In this paper, we propose the design of a reconfigurable surface plasmon polariton (SPP) wave adapter designed by transformation optics, which can control the confinement of SPP waves on un-even metal surfaces. The proposed plasmonic device is constructed using homogeneously tunable materials (i.e. liquid crystals) so that the corresponding SPP wave transmission can be reconfigured by applying different voltages. Different types of modified design are investigated. Their performance is verified by full-wave simulations. The proposed devices will pave the way towards developing tunable plasmonic devices.
