Circular polarization memory of light
Physical Review E, 2005Circular polarization memory of light multiply scattered by Mie particles is investigated. The mechanism of randomization of helicity is found, in general, to dominate light circular depolarization by particles of large size or a high refractive index while the mechanism of randomization of direction dominates for small particles of a lower refractive ...

Understanding and measuring circular polarization
IEEE Transactions on Education, 2003Many modern satellite and terrestrial point-to-point communications systems use circular polarization (CP) wave propagation in order to maximize the polarization efficiency component of the link budget. Therefore, in an undergraduate electromagnetics syllabus, an introduction to the topic of circular polarization is necessary to promote an ...

A monopole antenna with circular polarization
2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014A monopole antenna with coplanar-waveguide (CPW) feeding structure is developed for multiple wireless communication system integration. By tuning one of the CPW ground-plane widths can increase the impedance bandwidth. The circular polarization at 1.57 GHz is excited without adding extra design circuits.

A polarization selective surface for circular polarization
1988 IEEE AP-S. International Symposium, Antennas and Propagation, 2003The authors develop surfaces which will transmit a circularly polarized incident wave of one circularity and reflect a wave of opposite circular polarization. Preliminary results for typical circular polarization selective surfaces are given. These results clearly provide the proof of this principle.

Circular polarization in transparent circular patch with defected structure
2016 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2016This paper presents an optically transparent circular shaped microstrip patch antenna. The transparent circular microstrip antenna comprises a thin sheet of soda lime glass substrate with conductive ITO film coating for radiating patch and ground plane and is feed through a CPW feeding technique. The circular shaped patch is modified by inserting inset

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.
