Discovery of circularly polarised radio emission from SS 433 [PDF]

open access: yes, 1999
We report the discovery of circularly polarised radio emission from the radio-jet X-ray binary SS 433 with the Australia Telescope Compact Array. The flux density spectrum of the circular polarization, clearly detected at four frequencies between 1 - 9 ...

Generation of Circular Polarization of the Cosmic Microwave Background [PDF]

open access: yes, 2009
The standard cosmological model, which includes only Compton scattering photon interactions at energy scales near recombination, results in zero primordial circular polarization of the cosmic microwave background.

Radio Linear and Circular Polarization from M81* [PDF]

open access: yes, 2005
We present results from archival Very Large Array (VLA) data and new VLA observations to investigate the long term behavior of the circular polarization of M81*, the nuclear radio source in the nearby galaxy M81.

Circular polarization in atmospheric aerosols

open access: yesAtmospheric Chemistry and Physics, 2022
Abstract. Recent technological advances have demonstrated the feasibility of deploying spaceborne optical detectors with full polarimetric capabilities. The measurement of all four Stokes coefficients opens significant new opportunities for atmospheric aerosol studies and applications.

Probing the Circular Polarization of Relativistic Jets on VLBI Scales [PDF]

open access: yes, 2002
High resolution studies of circular polarization allow us see where it arises in a jet, study its local fractional level and spectrum, and compare these results to local measures of linear polarization and Faraday rotation.

Magnetically induced circular polarization

open access: yesPhysical Review A, 1987
Helium atoms excited to an aligned (1s3d)/sup 3/D state are produced by electron impact parallel to a magnetic field. The initial alignment of the atomic state evolves into an orientation with finite angular momentum along the magnetic field direction and thus gives rise to a circularly polarized component in the (1s3d)/sup 3/D..-->..(1s2p)/sup 3/P ...

Circular Polarization Laser Output Through Magnetic Switch

open access: yesIEEE Access, 2019
In order to obtain an integrated structure achieving controllable circular polarization and laser output at 1310 nm, the gain and loss microcavities, magnetic microcavity, and metal layers are used to form a compound structure system, and the 4 × ...

Grain Alignment in OMC1 as Deduced from Observed Large Circular Polarization [PDF]

open access: yes, 2009
The properties of polarization in scattered light by aligned ellipsoidal grains are investigated with the Fredholm integral equation method (FIM) and the T-matrix method (Tmat), and the results are applied to the observed circular polarization in OMC1 ...

Spin injection in Silicon at zero magnetic field [PDF]

open access: yes, 2009
In this letter, we show efficient electrical spin injection into a SiGe based \textit{p-i-n} light emitting diode from the remanent state of a perpendicularly magnetized ferromagnetic contact.

A Wideband Quad-Polarization Reconfigurable Metasurface Antenna

open access: yesIEEE Access, 2018
A low-profile wideband metasurface antenna with quad-polarization reconfiguration ability is presented in this paper. The proposed metasurface antenna is composed of a square patch, a metasurface formed by a lattice of 4 × 4 periodic metal plates,
