Efficient polarization converter for projection displays

Applied Optics, 1997
In the waveguiding limit, a twisted nematic liquid crystal cell behaves as an achromatic polarization rotator. We propose and demonstrate the application of such a polarization rotator to convert unpolarized light into linearly polarized light with almost 100% efficiency.

Broadband Linear to Circular Reflection Polarization Converter

2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019
A broadband linear to circular polarization converting surface is presented. The polarization reflector consists of a dogbone-shaped FSS separated from the metallic ground plane by a Teflon dielectric slab of thickness equal to 3.95 mm. The polarization converter is composed by a periodic arrangement of metallic particles, positioned in a square ...

Polarization-Insensitive Cross-Polarization Converter

IEEE Transactions on Antennas and Propagation, 2021
A transmission-type cross-polarization converter is designed based on a frequency selective surface (FSS) and is investigated theoretically and experimentally. The FSS structure is built up with rotationally asymmetric fourfold supercell. The subcell of each supercell is a monopole-via-monopole (MVM) module, which consists of a receiving monopole, a ...

Polarization-switching D/A converter

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2005
This paper describes a novel digital-to-analog (D/A) conversion technique, which uses the analog quantity polarization as a D/A conversion medium. It can be implemented by CMOS capacitors or by ferroelectric capacitors, which exhibit strong nonlinearity in charge versus voltage behavior.
