Reflection-type ultra-wideband terahertz polarization reconfigurable circular polarizer

摘要: The invention discloses a reflection-type ultra-wideband terahertz polarization reconfigurable circular polarizer, which is formed by M*N unit structures arranged periodically in the same horizontal plane. Each structure comprises metal floor layer, middle dielectric layer and double-open resonant square ring are stacked up sequence. an anisotropic two centrosymmetric L-shaped bars. polarizer high practicality, can convert linear polarized wave into efficiently within range, simple easy to process, still has good linear-circular conversion performance wide incidence angle characteristic; besides, adjusting parameters, be applied other frequency bands application prospect aspects of antenna design stealth technology like.
