Bifunctional Terahertz Metasurface for Transmissive Broadband Linear-to-Circular and Linear Polarization Conversion

IEEE Transactions on Terahertz Science and Technology, 2023
In this article, we experimentally demonstrate a bifunctional terahertz (THz) metasurface that can achieve broadband linear-to-circular polarization conversion (LCPC) and linear polarization conversion (LPC) in two different bands, respectively.

Terahertz Metagrating Emitters with Beam Steering and Full Linear Polarization Control.

Nano letters (Print), 2022
We report the realization of broadband THz plasmonic metagrating emitters for simultaneous beam steering and all-optical linear polarization control. Two types of metagratings are designed and experimentally demonstrated.

Spin-induced linear polarization of photoluminescence in antiferromagnetic van der Waals crystals

Nature Materials, 2020
Antiferromagnets are promising components for spintronics due to their terahertz resonance, multilevel states and absence of stray fields. However, the zero net magnetic moment of antiferromagnets makes the detection of the antiferromagnetic order and ...

Broadband and High-efficiency Linear Polarization Converter Based on Reflective Metasurface

Engineering Sciences, 2020
A linear polarization converter based on metasurface operating in reflection mode was demonstrated. Simulated results indicate that the polarization conversion ratio (PCR) of the polarization converter is more than 90% in the range of 4.73-10.93 GHz. The

Bremsstrahlung linear polarization

Canadian Journal of Physics, 1989
The dependence of the bremsstrahlung perpendicular and parallel triple differential cross sections and the linear polarization on the angles and energies of the incident and scattered electron and of the emitted gamma-ray has been studied in the high-energy small-angle hypothesis.

Bremsstrahlung linear polarization

Il Nuovo Cimento, 1960
This work presents a general quantitative description of the bremsstrahlung linear polarization on the basis of original experimental data and available theoretical calculations. The results give the dependence of the polarization ona) the initial electron kinetic energy,T0, in a range from 10−2 to 103 MeV,b) the photon energy in a range from 0.1T0 ...

Linear Polarization of Distant Quasars

Nature, 1970
MEASUREMENTS of the linear polarization of quasars at a wavelength of 49 cm (m49) have already shown that this parameter is correlated with spectral index α (ref. 1). We have now observed a more complete sample of 93 quasars, all of which have measured redshifts.
