Circular Polarization of Internal Bremsstrahlung
Physical Review, 1957A calculation is made of the circular polarization of the internal bramsstrahlung in allowed $\ensuremath{\beta}$-decay with the most general $\ensuremath{\beta}$-interaction. The polarization is found to rise from zero at the low-energy end of the spectrum to a maximum value at the high-energy end. This maximum value depends critically on the relative

TEM Modes and Circular Polarization
American Journal of Physics, 1963In this treatment of transverse electromagnetic waves circularly polarized waves of opposite senses are associated with a given positive frequency and the corresponding negative frequency. Linear polarization is thus obtained only as a superposition of circularly polarized waves.

Circular-polarization modulator
Nature Photonics, 2017Switching the handedness of circularly polarized light requires separately controlling the phases of orthogonal components while maintaining their magnitudes, ideally with gigahertz operation rates. Ultrafast switching has now been realized via all-optical control of birefringent metamaterials.

Superachromatic circular polarizer
Measurement Science and Technology, 2000We 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, 1963A 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.

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, 2004Of 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.

A Nonreciprocal Circular Polarizer
IEEE Transactions on Microwave Theory and Techniques, 1967A 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
