A THz fiber polarization splitter based on anti-resonant hollow-core fiber with the asymmetric dual-suspended cores

Frontiers in Physics, 2023
In this paper a novel THz fiber polarization splitter based on anti-resonant hollow-core fiber with asymmetric dual-suspended cores has been proposed. For the proposed polarization splitter, the ultra-low confinement loss and great polarization splitting

Experimental demonstration of a dual-frequency laser free from anti-phase noise [PDF]

, 2012
A reduction of more than 20 dB of the intensity noise at the anti-phase relaxation oscillation frequency is experimentally demonstrated in a two-polarization dual-frequency solid-state laser without any optical or electronic feedback loop.

Dual-Band Omnidirectional Circularly Polarized Antenna

IEEE Transactions on Antennas and Propagation, 2013
A dual-band omnidirectional circularly polarized antenna is proposed. The antenna comprises back-to-back microstrip patches fed by a coplanar waveguide. A very low frequency ratio of 1.182 has been achieved, which can be easily tuned by adjusting four lumped capacitors incorporated into the antenna.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

FEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Design and simulated characterization of the dual-band polarizer based on metasurface structure

AIP Advances
Dual-band polarizers must simultaneously exhibit high transmittance and bandwidth efficiency in fields such as polarization navigation and efficient detection. However, in most studies, the detection of dual bands is inefficient.

Microphysical Insights From Dual Polarization Spectral Observations in Updraft and Mixed-Phase Precipitation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study presents dual polarization spectral analysis over updraft environments in thunderstorms. The composition and interaction of particle in updrafts environments are analyzed using the expansion that the spectral polarimetric provides in radar ...

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Design and Bolometer Characterization of the SPT-3G First-year Focal Plane [PDF]

, 2018
During the austral summer of 2016-17, the third-generation camera, SPT-3G, was installed on the South Pole Telescope, increasing the detector count in the focal plane by an order of magnitude relative to the previous generation.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Exceptional Extended Dual Polar Spaces

European Journal of Combinatorics, 1997
It is considered an extended dual polar space (EDPS). An EDPS \({\mathcal G}\) is called affine if there is a flag-transitive automorphism group \(G\) and a normal subgroup \(T\) in \(G\) such that \(T\) acts regularly on the set of elements of type 1 in \({\mathcal G}\). Theorem. Let \({\mathcal G}\) be an EDPS whose rank is greater than or equal to 3
