Abstract

Terahertz (THz) band has been attracting an enormous reputation due to the paucity of natural materials in this range. Artificially flat thin films, called metasurfaces, plead the research community owing to their unprecedented features to manipulate the scattering properties of electromagnetic (EM) waves. Capitalizing on these unique attributes of the metasurfaces, a wideband polarization converter is investigated for THz frequencies. The proposed metasurface rotates the incoming EM wave into its cross-component over a broad spectral range from 1 THz to 1.75 THz. The designed polarization conversion metasurface (PCM) manifests above 90% efficiency, having a bandwidth of 0.75 THz. This unit cell is also scalable to other operating regimes such as microwave and visible, just by scaling its physical dimensions. This kind of wideband PCM remains prudent for various applications of radar cross-section reduction (RCSR), imaging, communication, etc.
