We develop a more general methodology for a dual photoelastic modulator (PEM) system that is used for the determination of the Stokes parameters of an arbitrary light beam. This allows for a degree of arbitrariness in the setting of the retardation amplitudes of both PEMs, thus permitting a robust and effective optimization of the detection system. Various experimental issues are considered and...

Maps of Galactic polarized continuum emission at 1408, 1660, and 1713 MHz towards the local Taurus molecular cloud complex were made with the Effelsberg 100-m telescope. Minima in the polarized emission which are located at the boundary of a molecular cloud were detected. Beside high rotation measures and unusual spectral indices of the polarized intensity, these features are associated with th...

The internal depolarization of linearly polarized radio synchrotron emission of spiral galaxies by differential Faraday rotation in regularmagnetic fields andbyFaradaydispersion in random magnetic fields is formulated in one dimension as a function of radio wavelength λ. The random fields are modeled as a number of cells along the line of sight which obey a Kolmogorov spectrum in size and in fi...

During the past 2 yr, we have been theoretically and experimentally investigating coherent backscattering ~CBS! of near-resonant light in a sample of cold rubidium atoms @1–3#. CBS is an interference effect in the multiple scattering regime of propagation inside random media, yielding an enhancement of the backscattered light intensity @4#. This interference is very robust and can be destroyed ...

The four wavenumbers associated with planewave propagation in a Faraday chiral medium (FCM) with relatively huge magnetoelectric coupling give rise to enhanced possibilities for negative–phase–velocity propagation and therefore negative refraction. They can also give rise to the phenomenon of negative reflection. In particular, for a nondissipative example, we deduced that an incident plane wav...

Transmission of light through an atomic sample placed between crossed polarizers in a magnetic field is jointly determined by Faraday rotation and net absorption: transmission increases with rotation and decreases with absorption. Both rotation and absorption are proportional to the atomic density N0, hence, in a certain range of N0, the two effects may compete yielding a distinct density depen...

A new polarimetric calibration method using polarization orientation angle shifts at built-up areas and standard calibrators is studied. Calibration matrices were derived from datasets of the Gifu and the JAXA Tomakomai calibration sites, which are almost the same as those by JAXA. Faraday rotation angels in observed datasets can be estimated. Two estimated Faraday rotation angles were reasonable.

Introduction: Magneto-optics (MO) technology is believed to be far more advanced in the former Soviet Union when compared to the US. This is evidenced by the existence of factories geared for the production of Yttrium Iron Garnet (YIG) wafers. The potential advantages to MO Crystal Technology over other magnetic sensing technologies are (1) light weight and compact construction, (2) low cost, a...

A sensitive polarization modulation technique uses photoelastic modulation and heterodyne detection to simultaneously measure the Faraday rotation and induced ellipticity in light transmitted by semiconducting and metallic samples. The frequencies measured are in the midinfrared and correspond to the spectral lines of a CO2 laser. The measured temperature range is continuous and extends from 35...
