    Abstract

    Terahertz (THz) radiation is gaining momentum in biology, medicine, communication, security, chemistry, and spectroscopy applications. To expand the usability of terahertz radiation the man-made metal-dielectric composite metamaterials are typically considered owing to their ability to effectively manipulate electromagnetic waves. The possibilities of light manipulation can be extended even more by involving new active materials as a structural component – such as, for example, graphene. Its prominent conductivity tunability through the electrochemical potential change allows converting a multilayer graphene/dielectric structure into an artificial medium with widely varying properties – transparent or opaque, plasmonic, low-index or high-index dielectric – in a certain THz or infra-red frequency range. This chapter presents several examples of effective THz components like absorbers, modulators, and filters based on graphene-dielectric multilayers
