Optical properties and enhanced Faraday rotation in three-layer hybrid magneto-plasma crystals with C4h symmetry

open access: yesResults in Physics
We investigate the optical properties and magneto-optical (MO) Faraday effect of a type of hybrid magneto-plasma crystal (HMPC) that is composed of a magnetic layer sandwiched between two Ag layers containing an array of holes.

Turbulent Structure in Supernova Remnants G46.8−0.3 and G39.2−0.3 from THOR Polarimetry

open access: yesThe Astrophysical Journal, 2023
We present the continued analysis of polarization and Faraday rotation for the supernova remnants (SNRs) G46.8−0.3 and G39.2−0.3 in L -band (1–2 GHz) radio continuum in The H i /OH/Recombination line (THOR) survey.

Faraday effect in CoPt-CaF2 nanogranular films with hard magnetic property for magnetic-field-free faraday devices

open access: yesFrontiers in Physics, 2022
Magneto-optical Faraday devices, such as optical isolators, require a structure to apply a magnetic field to the incorporated magneto-optical material.

Faraday rotation and polarization gradients in the jet of 3C~120: Interaction with the external medium and a helical magnetic field?

open access: yes, 2008
We present a sequence of 12 monthly polarimetric 15, 22, and 43 GHz VLBA observations of the radio galaxy 3C 120 revealing a systematic presence of gradients in Faraday rotation and degree of polarization across and along the jet.

Fabry-Perot enhanced Faraday rotation in graphene

open access: yes, 2013
We demonstrate that giant Faraday rotation in graphene in the terahertz range due to the cyclotron resonance is further increased by constructive Fabry-Perot interference in the supporting substrate.

Improving the Topside Profile of Ionosonde with TEC Retrieved from Spaceborne Polarimetric SAR

open access: yesSensors, 2019
Signals from spaceborne polarimetric synthetic aperture radar will suffer from Faraday rotations when they propagate through the ionosphere, especially those at L-band or lower frequencies, such as signals from the Phased Array type L-band Synthetic ...

Faraday Rotation Spectroscopy of Quantum-Dot Quantum Wells

open access: yes, 2005
Time-resolved Faraday rotation studies of CdS/CdSe/CdS quantum-dot quantum wells have recently shown that the Faraday rotation angle exhibits several well-defined resonances as a function of probe energy close to the absorption edge.

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Atomic and photonic entanglement concentration via photonic Faraday rotation

open access: yes, 2012
We propose two alternative entanglement concentration protocols (ECPs) using the Faraday rotation of photonic polarization. Through the single-photon input-output process in cavity QED, it is shown that the maximally entangled atomic (photonic) state can
