Shape dependence of THz metasurface and its applications

THz waves are receiving great attention in, for example, medical imaging as well as 6G communication. Basic research using THz waves for such applications is being actively conducted. However, since the commercially available THz components are still bulky and difficult to use, the need for a compact THz system has been growing. In this context, metasurfaces facilitating high transmission and full phase control have great potential. This project aims to find and verify optimized metasurface designs for beam focusing and generation of structured THz light carrying orbital angular momentum, by quantitatively evaluating the optical properties of a large set of metasurface shapes. Eventually, we envision that the outcome of this project can contribute to the development of a compact THz system for a wide range of industrial applications.
