Dual polarization split lenses [PDF]
Optics Express, 2017 We report the realization of polarization sensitive split lens configurations. While split lenses can be used to easily generate different types of controlled structured light patterns, their realization has been limited so far to scalar beams. Here we propose and experimentally demonstrate their generalization to vectorial split lenses, leading to ...

A Microstrip Antenna Achieves Dual Polarization Conversion by Rotating Metasurface
IEEE AccessTo expand the channel capacity of a traditional single-polarization reconfigurable antenna, a design method for a dual-polarization reconfigurable microstrip antenna loaded with a passive metasurface was proposed.

Assessing Single-Polarization and Dual-Polarization TerraSAR-X Data for Surface Water Monitoring [PDF]
Remote Sensing, 2018 Three synthetic aperture radar (SAR) data classification methodologies were used to assess the ability of single-polarization and dual-polarization TerraSAR-X (TSX) data to classify surface water, including open water, ice, and flooded vegetation.

Discrete Mathematics, 2006 AbstractThe smallest number of points of an incidence structure which is self-dual but not self-polar is 7. For non-binary structures (where a “point” may occur more than once in a “block”) the number is 6.

Estimation of the Degree of Polarization for Hybrid/Compact and Linear Dual-Pol SAR Intensity Images: Principles and Applications [PDF]
, 2013 Analysis and comparison of linear and hybrid/compact dual-polarization (dual-pol) synthetic aperture radar (SAR) imagery have gained a wholly new importance in the last few years, in particular, with the advent of new spaceborne SARs such as the Japanese

Hydrometeor partitioning ratios for dual-frequency space-borne and polarimetric ground-based radar observations [PDF]
Atmospheric Measurement TechniquesConventional radar-based hydrometeor classification algorithms identify the dominant hydrometeor type within a resolved radar volume, while newer techniques estimate the proportions of individual hydrometeor classes (hydrometeor partitioning ratios, HPRs)

Dual-Polarization Phase Retrieval Receiver in Silicon Photonics
, 2023 We demonstrate a silicon photonic dual-polarization phase retrieval receiver. The receiver recovers phase from intensity-only measurements without a local oscillator or transmitted carrier. We design silicon waveguides providing long delays and microring

A Low-Profile Dual-Polarized Magneto-Electric Dipole Antenna for 5G Applications
Applied Sciences, 2022 A low-profile dual-polarized magneto-electric dipole (MED) is presented in this communication. The low profile was achieved using meander slots on the vertical magneto dipole, reducing the antenna height to 0.15λ0, where λ0 is the wavelength of the ...
