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.

Polarization converting antenna

1971 Antennas and Propagation Society International Symposium, 1971
A new type of polarization converting antenna has been introduced. This antenna receives vertically polarized signals and re-radiates it with horizontal polarization, or vice-versa. This type of polarization converting antenna is useful for responder applications. The responder is a passive version of a transponder.

Unidirectional magnetooptic polarization converters

Journal of Lightwave Technology, 1999
Inclination of the bias magnetization in a magnetooptic waveguide yields both nonreciprocal phase shifts and polarization conversion. This enables the design of unidirectional polarization converters, i.e., waveguides that switch between orthogonal polarizations for one direction of light propagation, but keep the polarization state for light ...
