Wideband Metasurface-Based Reflective Polarization Converter for Linear-to-Linear and Linear-to-Circular Polarization Conversion

IEEE Antennas and Wireless Propagation Letters, 2018
A wideband reflective polarization converter based on metasurface is proposed in this letter. This converter can transform a linearly polarized (LP) incident electromagnetic (EM) wave into its orthogonal LP reflection wave in a lower band, and a ...

Superachromatic circular polarizer

Measurement Science and Technology, 2000
We present a design for a superachromatic circular polarizer that can be constructed with conventional, two-element, achromatic half-wave and quarter-wave retarders and used over the whole range of visible wavelengths.

A wave polarization converter for circular polarization

IEEE Transactions on Antennas and Propagation, 1963
A linearly polarized wave may be converted to a circularly polarized wave by means of a panel which provides 90\deg difference in transmission phase between two crossed linear components. This phase difference is obtained over a wide frequency band by means of thin sheets containing both inductive and capacitive shunt susceptance.

Circular Polarized LCD

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1998
Abstract Novel LCD, which transmits circularly polarized light, is reported. The circular polarized light enables us to see the LCD screen through polarized sunglasses. It is developed for outdoor application, such as mobile computing, car navigator, and so on. The circular light is achieved by placing additional quarter wave film upon the screen.

Circular Polarization of Starlight

Astrophysics, 2004
Of the 7500 stars cited in the Catalog of starlight polarization, those which satisfy the condition P obs ≤ σρ% and A V ≥ 0m.5 are selected. It is presumed that the selected stars (n=216) have circularly polarized light.

Antennas for Circular Polarization

Proceedings of the IRE, 1948
A formula is derived to give the variation in received voltage when an elliptically polarized antenna is rotated in a plane ransverse to the direction of propagation of the incident elliptically tolarized wave. It is shown that a circularly polarized antenna will pot receive any of its transmitted energy which is reflected from a nighly conducting ...

A Nonreciprocal Circular Polarizer

IEEE Transactions on Microwave Theory and Techniques, 1967
A nonreciprocal circular polarizer has been developed. This ferrite device converts linear polarization propagating in rectangular waveguide into circular polarization propagating in circular waveguide. The sense, right- or left-hand, of the circular polarization is determined by the direction of a longitudinal magnetic field applied to the ferrite. If
