Polarization-insensitive tunable terahertz polarization rotator
Optics Express, 2019 A rotation-angle variable polarization rotator is proposed and demonstrated using an all-dielectric metasurface doublet. Such a transmissive device can conveniently rotate the polarization of incident light by any desired angles by mechanically changing the relative angle of the double metasurface layers regardless of the incident state of polarization.

Polarization insensitive imaging through polarization gratings
Optics Express, 2009 Liquid crystal polarization gratings exhibit high diffraction efficiency (approximately 100%) in thin material layers comparable to the radiation wavelength. We demonstrate that they can be combined for polarization-insensitive imaging and optical switching applications.

Polarization-Independent Filter Based on 2-D Crossed Grating Under Oblique Incidence
IEEE Photonics Journal, 2018 The existing polarization-insensitive filters based on two dimensional (2-D) grating are mostly under normal incidence. However, in filtering optical devices, the normal incidence regime is usually avoided because it requires the use of beam separators ...

Depolarizing Chipless Tags with Polarization Insensitive Capabilities [PDF]
Electronics, 2021 A novel depolarizing chipless tag configuration with high angular insensitivity is presented. The basic tag comprises two dipole resonators arranged with a relative rotation of 45°. The proposed configuration improves the depolarization properties performance of a single dipole over the ground plane which provides a peak with perfect polarization ...
