Deeply subwavelength electromagnetic Tamm states in graphene metamaterials

Smirnova, Daria; Buslaev, P. I; Iorsh, I. V.; Shadrivov, Ilya; Belov, Pavel; Kivshar, Yuri

Description

We study localized modes at a surface of a multilayer structure made of graphene layers separated by dielectric layers. We demonstrate the existence of deeply subwavelength surface modes that can be associated with the electromagnetic Tamm states, with the frequencies in the THz frequency range the negative group velocities. We suggest that the dispersion properties of these Tamm surface modes can be tuned by varying the thickness of a dielectric cap layer.
