A tunable terahertz metamaterial absorber composed of elliptical ring graphene arrays with refractive index sensing application
In this paper, we demonstrate a tunable absorber composed of periodically patterned elliptical ring graphene metamaterial arrays. An absorption peak at 53.6μm with the maximum absorption of 49.2% of pure graphene layer has been realized. The effects of different parameters are studied by the Finite...
