Paper Abstract

In this work, we propose and theoretically investigate the first dynamically tunable metasurface based on new twodimensional (2D) material - multi-layer graphene (MLG). As a basis for metasurface development, the results of experimental studies in THz frequency band of 80-layered graphene on dielectric substrate under external optical pumping were used. The metasurface consist of the Polymethylpentene (TPX) substrate and cross-shaped MLG pattern. In addition, the structure of the metasurface is very simple and can be fabricated by chemical vapor deposition and laser engraving. Proposed non-metallic metasurface is high-potential candidate for designing an active THz devises.
