In this work, three metasurfaces with a patch-like, a strip-like, and a fishnet-like unit cell are compared in terms of their surface impedance for different angles of incidence in the terahertz range. The fishnet-like metasurface shows a TE-TM polarization independent behavior and a spatially nondispersive response, thus offering very interesting possibilities for the design of efficient Fabry-Perot cavity leaky-wave antennas at terahertz frequencies.

Abstract
In this work, three metasurfaces with a patch-like, a strip-like, and a fishnet-like unit cell are compared in terms of their surface impedance for different angles of incidence in the terahertz range. The fishnet-like metasurface shows a TE-TM polarization independent behavior and a spatially nondispersive response, thus offering very interesting possibilities for the design of efficient Fabry-Perot cavity leaky-wave antennas at terahertz frequencies.File in questo prodotto:
