Achieving 100% amplitude modulation depth in the terahertz range with graphene-based tuneable capacitance metamaterials

Achieving 100% amplitude modulation depth in the terahertz range with graphene-based tuneable capacitance metamaterials

Abstract Effective control of terahertz radiation requires fast and efficient modulators with a large modulation depth—a challenge that is often tackled by using metamaterials. Metamaterial-based active modulators can be created by placing graphene as a tuneable element shunting regions of high elec...
