Tunable and broadband coherent perfect absorbers with nonlinear and amplification performance based on asymmetric bifacial graphene metasurfaces
Tianjing Guo, Christos Argyropoulos
We present an asymmetric bifacial graphene metasurface to realize tunable and broadband coherent perfect absorption (CPA) at terahertz (THz) frequencies. The proposed design is com…

Tunable THz generation and enhanced nonlinear effects with active and passive graphene hyperbolic metamaterials
Boyuan Jin, Tianjing Guo, Liang Zhu +2
The active and nonlinear graphene properties are limited due to weak light matter interaction between the ultrathin graphene and the incident light. In this work, we present enhanc…
