Circular Polarization in Scintillating Sources

Circular Polarization from Stochastic Synchrotron Sources

The transfer of polarized radiation in stochastic synchrotron sources is explored by means of analytic treatment and Monte Carlo simulations. We argue that the main mechanism responsible for the circular polarization properties of compact synchrotron sources is likely to be Faraday conversion and that, contrary to common expectation, a significant rate of Faraday rotation does not necessarily i...

A New Circular Polarization Metamaterial Ferrite Phase Shifter

In this paper, a new X band Metamaterial (MTM) based ferrite phase shifter is presented. The phase shifter is excited by circular polarized wave base on combination of TE10 and TE01 modes in a square waveguide. In order to synthesize negative refractive index metamaterial (NIM), negative permeability of ferrite slabs in extraordinary mode is mixed with the negative permitivity of printed period...

Circular Polarization Variability in Extragalactic Sources on Time Scales of Months to Decades

We present previously unpublished circular polarization (cp) measurements at 4.8 and 8.0 GHz made with the University of Michigan 26-meter prime focus telescope during 1978–1984 and results of a new observational program during the past two years. Based on the preliminary analysis of our recent data, eight sources were detected at 4.8 GHz with average degrees of cp ranging from ≤ 0.1% to ≥ 1%. ...

Anisotropy-dependent circular polarization spectroscopy

We have experimentally investigated the anisotropy-dependent circular polarization spectra of the Cs 6sS1/2→6p P3/2→10s S1/2 double-resonance transition in the presence of Ar. Satisfaction of doubleresonance condition, achieved by use of a two-photon two-color pulse laser excitation scheme, was monitored by measurement of the intensity of the 9pP1/2→6s S1/2 cascade fluorescence at 361.73 nm. In...
