摘要： A plasmonic phase modulator is provided. The modulator has a conductive layer, and a dielectric layer disposed on the conductive layer. A plasmonic layer is disposed on the dielectric layer. A plasmonic layer is disposed on the dielectric layer. The plasmonic layer is conductive to surface plasmon polariton (SPP) waves. The plasmonic layer may be, for example, a graphene sheet. A voltage signal source is operatively connected between the conductive layer and the plasmonic layer for modulating a propagation speed of an SPP wave propagating on the plasmonic layer.

摘要： A hybrid radiating element may comprise a dielectric substrate having a thickness, a top surface and a bottom surface, and an electrically conductive patch disposed on the top surface of the dielectric substrate. The hybrid radiating element may further comprise a graphene stub disposed on the top surface of the dielectric substrate. The graphene stub may be contiguous with, and electrically coupled to, the electrically conductive patch. The hybrid radiating element may further comprise an electrically conductive layer disposed on the bottom surface of the dielectric substrate. An array of hybrid radiating elements may be arranged in a grid pattern of M rows and N columns. A codebook set of biasing voltages may be arranged to drive the radiating elements in the array as a phase transformation matrix, thereby manipulating the reflection of an incoming electromagnetic wave.
