Abstract
Metasurfaces based on VO2 which properties are switchable by using near IR light or local resistive heating are of great interest for novel sub-THz/THz photonic devices including active filters and THz generators. We report on design and study of elements for hybrid metasurface with narrow resonance in 0.7-1.3 THz range based on Au bow-tie antennas and VO2 for THz switchable application.
