Guided-Wave Properties of Slow-Wave Substrate-Integrated Waveguide Patterned with Non-Uniform Metasurface Unit Cells with Various Degrees of Rotation

open access: yesPhotonics, 2023
A novel slow-wave waveguide structure is proposed, the guided-wave properties of which can be controlled by the rotation of nonuniform metasurface elements loaded on the surface of the substrate-integrated waveguide.
