All-dielectric polarization-sensitive metasurface for terahertz polarimetric imaging.

ABSTRACT: Terahertz polarimetric imaging, capable of capturing not only intensity profiles but also the polarization states of the incident pattern, is an essential technique with promising applications such as security scans and medical diagnoses. Recently, a novel approach for terahertz imaging has been proposed using a metasurface absorber that converts terahertz light into a temperature profile. However, polarization remains indistinguishable in the imaging process due to the isotropic geometry of the metasurface. To address this issue, this study introduces an all-dielectric, polarization-sensitive metasurface absorber and showcases its suitability for terahertz polarimetric imaging. Optical and thermal simulations confirm that the polarization dependence of our metasurface is translated into t
