In this article, airborne broadband (maximum 400 MHz bandwidth) C-band circularly polarized synthetic aperture radar (SAR) is proposed and developed for further study on compact (CP SAR) system using circular polarization. This article explains the scattering characteristic of polarization as concept SAR, configuration, RF antenna, ground test, flight test SAR in Hinotori-C2 (Firebird-C2) missi...

In this paper, a wideband circularly polarized (CP) filtering hybrid antenna is presented. The liquid dielectric resonator (DR) excited by microstrip-coupled cross-slot to generate CP radiation. Four inverted L-shaped strips are loaded on the ground plane introduce an additional resonant point, then two adjacent axial ratio (AR) minima combined improve bandwidth of single-feed antenna. By etchi...

The angular distribution of photoelectrons predicted for elliptically polarized light is shown to be the same as that predicted for partially polarized light having incoherent perpendicular electric field components equal to the electric field components along the major and minor axes of the ellipse. Increasing use by atomic experimenters of synchrotron radiation, which is known to be elliptica...

This paper describes the concept, design, and measurement of a multi-band circularly polarized printed slot antenna with a single microstrip feed line. The antenna design for circular polarization (CP) at 1.5 GHz for GPS, 2.4 GHz for Bluetooth, and 3.75GHz for WiMAX application is given. The proposed antenna also provides a fourth linear polarized band over 5.2 to 6 GHz covering the WLAN band. ...

We investigate, both theoretically and experimentally, the phenomenon of polarization rotation of a weak, linearly-polarized optical (probe) field in an atomic system with multiple three-level electromagnetically induced transparency (EIT) sub-systems. The polarization rotation angle can be controlled by a circularly-polarized coupling beam, which breaks the symmetry in number of EIT subsystems...

In the proposed E-166 experiment at SLAC, 50 GeV electrons pass through a helical undulator, and produce circularly polarized photons, which interact with a tungsten target and generate longitudinally polarized positrons. The background is an important issue for an experiment under consideration. To address this issue, simulations were performed with the code GEANT3 to model the production of s...

We study spatiotemporal pattern formation associated with the polarization degree of freedom of the electric eld amplitude in a mean eld model describing a Kerr medium in a cavity with at mirrors and driven by a coherent plane-wave eld. We consider linearly as well as elliptically polarized driving eld and situations of self-focusing and self-defocusing. For the case of self-defocusing and line...
