Excitation of surface waves in the photonic crystal/graphene structure for terahertz frequency range

Abstract

Photonic crystals are one of the most remarkable metamaterials for electromagnetic waves manipulation for last decades, therefore they can be used as filters, waveguides, polarization changers, superlenses, superprisms, etc. As well today graphene has attracted considerable attention due to the unusual properties. In this paper the excitation of surface waves in the photonic crystal bounded by graphene layer was investigated for terahertz frequency range from 0.1 to 1 THz. Peaks of transmissivity in band-gaps of photonic crystal that caused by excitation of surface waves were obtained. The control of frequency position of peaks by temperature and magnetic field was demonstrated.
