Modified design of obtaining dual-circular polarization radiation of a single-feed square microstrip antenna are proposed and experimentally studied. The proposed single-feed dual circular polarized design is achieved by inserting four Tshaped slits at the patch edges of a square microstrip antenna. Details of the design considerations of the proposed antenna are described, and experimental res...

Mean pulse profiles and polarization properties are presented for nine southern pulsars. The observations were made using the Parkes radio telescope at frequencies near 1330 MHz; three of the nine pulsars were also observed at 660 MHz. A very high degree of circular polarization was observed in PSR J1603−7202. Complex position angle variations which are not well described by the rotating-vector...

Abstract. Recent technological advances have demonstrated the feasibility of deploying spaceborne optical detectors with full polarimetric capabilities. The measurement all four Stokes coefficients opens significant new opportunities for atmospheric aerosol studies and applications. While considerable amounts attention been dedicated to sensors sensitivity total intensity linear polarization (r...

Printed reflectarrays combine certain advantages of reflector antennas and phased arrays. One major hurdle in the designing of reflectarrays is the compensation of phase difference between various elements. This paper presents reviews of various techniques for phase compensation, like using variable sizes of the patch, adding stubs of variable lengths and use of variable size slots on the groun...

collinear configuration, in which the laser wave is linearly polarized with electric field E parallel to the initial electron momentum p 0, is the optimal configuration for the relativistic reversal. In that case, the transverse PF reverses its direction when the incident momentum is p0=mc. The reversal effect vanishes in the cases of circular and linear with E p 0 polarizations. We have discov...

We report the first observation of ionization of Rydberg atoms by subpicosecond, circularly polarized THz radiation. The field amplitude in these pulses is non-negligible for only one-quarter of an optical cycle. The experiment is performed in the short-pulse regime, where the duration of the ionizing pulse is shorter than the classical Kepler period of the Rydberg electron. We find that the io...

Monitoring results are presented for the Stangellini 1 Jy GHz-peaked-spectrum source sample, illustrating that several members exhibit variability in total flux and/or linear polarization over timescales of order a decade. The variability occurs while the spectrum, based on the integrated fluxes, remains steep and characteristic of a transparent source. Total flux variability is unexpected in v...

The circular polarization and the absolute intensity of the elliptically polarized synchrotron radiation were measured in the VUV range as functions of the wavelength and of the vertical emission angle with respect to the orbit plane of the 2.5 GeV synchrotron in Bonn. In the wavelength range from 100 to 40 nm the absolute intensity and the circular polarization of the radiation with a bandwith...

The intermediate polar RX J1712.6-2414, discovered by Buckley et al. (1995), turned out to have a phasedependent circular polarization of up to −5% in the Ic band, the largest value observed in any intermediate polar. By comparing the slope of the observed polarized flux with theoretical models, Buckley et al. (1995) obtained an estimate of 8 MG for the magnetic field strength. In this fit, onl...
