Interstellar Circular Polarization [PDF]
Monthly Notices of the Royal Astronomical Society, 1972 This paper shows that optical observations of circular polarization produced by aligned interstellar grains could yield valuable information about the grain material. The interstellar medium is known to be linearly dichroic from observations of interstellar linear polarization.

Circular Polarization in Scintillating Sources [PDF]
Symposium - International Astronomical Union, 2001 We discuss the detection of variable circular polarization (CP) in several scintillating radio sources: PKS 1519-273, PKS 0405-385 and Sgr A*. In all cases the CP is variable, with the fractional variability in the CP greatly exceeding that in total intensity.

Circular polarization signals of cloudy (exo)planets
, 2018 The circular polarization of light that planets reflect is often neglected because it is very small compared to the linear polarization. It could, however, provide information on a planet's atmosphere and surface, and on the presence of life, because ...

Dispersion Analysis of Twist-Symmetric Dielectric Waveguides
Photonics, 2021 We propose a circular twist-symmetric dielectric waveguide that is polarization-selective. In the practical implementation of optical fibers, a selective circular polarization is more convenient than its linearly polarized counterpart where previous ...

Ultrafast circular polarization oscillations in spin-polarized vertical-cavity surface-emitting laser devices [PDF]
, 2010 Spin-polarized lasers offer new encouraging possibilities for future devices. We investigate the polarization dynamics of electrically pumped vertical-cavity surface-emitting lasers after additional spin injection at room temperature.

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Polarization immunity of magnetoresistivity response under Microwave excitation
, 2007 We analyze theoretically the dependence of the microwave polarization sate and sense on the magnetoresistivity response of two-dimensional electron systems. Linear and circular polarization have been considered with different senses and directions.

Circular polarization from linearly-polarized-laser-beam collisions [PDF]
Physical Review A, 2014 To probe the nonlinear effects of photon-photon interaction in the quantum electrodynamics, we study the generation of circular polarized photons by the collision of two linearly polarized laser beams. In the framework of the Euler-Heisenberg effective Lagrangian and the Quantum Boltzmann equation for the time evolution of the density matrix of ...
