Plasmonic Terahertz Amplification in Graphene-Based Asymmetric Hyperbolic Metamaterial

Plasmonic Terahertz Amplification in Graphene-Based Asymmetric Hyperbolic Metamaterial

We propose and theoretically explore terahertz amplification, based on stimulated generation of plasmons in graphene asymmetric hyperbolic metamaterials (AHMM), strongly coupled to terahertz radiation. In contrast to the terahertz amplification in resonant nanocavities, AHMM provides a wide-band THz...
