Abstract

Functional terahertz (THz) devices such as tunable polarizers, modulators, filters and absorbers are on demand. Graphene, a monolayer of carbon atoms, allows for tuning its THz conductivity through the Fermi level change. Graphene layers structured at the subwavelength scale form metamaterial which can have very unusual electromagnetic properties and thus expanding the range of its application for THz devices [1]. Usually graphene metamaterial based devices are designed straight through numerical simulations [2-4] and that requires time-consuming multiple variables analysis.
