Airborne Circularly Polarized Synthetic Aperture Radar

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
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 airborne compact polarized synthetic aperture radar (CP SAR) system using circular ...

Trap-assisted circularly polarized organic photodetector [PDF]

Nature Communications
The innovative design of π-conjugated molecules enables the creation of chiral π-systems that selectively interact with circularly polarized light. In circularly polarized organic photodetectors, the use of π-conjugated molecules with highly dissymmetric

Effect of Femtosecond Laser Polarization on the Damage Threshold of Ta₂O₅/SiO₂ Film

Applied Sciences, 2022
The study used linearly and circularly polarized femtosecond pulsed lasers to irradiate a Ta2O5/SiO2 film. Firstly, the damage thresholds of the film for linearly and circularly polarized femtosecond pulsed lasers were measured in 1-on-1 mode.

Experimental verification of selection rules for circularly polarized high harmonics from a solid [PDF]

EPJ Web of Conferences, 2019
We experimentally verify selection rules for circularly polarized high harmonics from solids by using single-color circularly polarized mid-infrared pulses. Our result offers a novel way to produce circularly polarized, coherent short-wavelength light.

Switchable Chiral Metasurface for Terahertz Anomalous Reflection Based on Phase Change Material

Applied Sciences, 2022
A switchable chiral metasurface based on a phase change material Ge2Sb2Te5, which can switch between a right-handed circularly polarized mirror and a left-handed circularly polarized mirror, is theoretically discussed.

A complex amplitude control method of metasurface based on full phase modulation

Results in Physics, 2023
Unlike the Pancharatnam-Berry phase and spin-decoupled metasurface, which only modifies the phase of the cross-polarization components, the full-phase modulation metasurface achieves independent wavefront control of the co– and cross-polarization ...

Scattering of circularly polarized radiation [PDF]

The Journal of Physical Chemistry, 1983
The differential refraction and absorption of circularly polarized light was applied by Henry Eyring and co-workers to study the configuration and conformation of small molecules. The differential scattering as a function of angle of circularly polarized light can provide structural information about large scattering systems.

Aggregation-induced emission from optically active X-shaped molecules based on planar chiral [2.2]paracyclophane

Scientific Reports, 2023
An optically active π-stacked molecule was synthesized incorporating planar chiral [2.2]paracyclophane and o-carborane units to impart circularly polarized luminescence and aggregation-induced emission properties to the molecule. The molecule exhibited a
