A Wideband Quad-Polarization Reconfigurable Metasurface Antenna
IEEE Access, 2018 A low-profile wideband metasurface antenna with quad-polarization reconfiguration ability is presented in this paper. The proposed metasurface antenna is composed of a square patch, a metasurface formed by a lattice of 4 × 4 periodic metal plates,

Cavity-based linear-to-circular polarization converter
Optics Express, 2017 This paper presents a polarization converter to convert a linearly polarized (LP) incident wave into an outgoing circularly polarized (CP) wave. It is constructed by a 2D array of thin cavities, with each cavity etched with three slots. The front slot is used to couple the LP wave into the cavity, while the backside orthogonal slots are utilized to ...

Optical Polarization Sensor Based on a Metalens
Sensors, 2022 We investigated an optical microsensor of the polarization state of a laser light based on a metalens. In contrast to known polarization sensors based on metasurfaces that deflect different polarization types using various angles to the optical axis, the

Fusion of polarimetric channel information of PALSAR data for land cover classification
Geomatics, Natural Hazards & Risk, 2014 Fully polarimetric radars are capable of preserving detailed information about the targets because of the amplitude and phase information they contain which helps in distinguishing different scattering mechanisms.

Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]
, 2012 We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.
