A dynamically-tunable graphene-based fano metasurface

Abstract

A planar graphene metasurface with rectangular holes, which is capable of supporting a dynamically tunable Fano resonance at Terahertz (THz) frequencies, is proposed. The rectangular hole is patterned asymmetrically within the metasurface's unit cell to “brighten” an originally-dark quadrupolar surface plasmon mode. Fano resonance is achieved via the… (More)
