Frontiers in Optics 2014, 2014 We report the implementation of a tunable beam displacer, composed of a polarizing beam splitter (PBS) and two mirrors, that divides an initially polarized beam into two parallel beams whose separation can be continuously tuned. The two output beams are linearly polarized with either vertical or horizontal polarization and no optical path difference is

Tunable Axion Plasma Haloscopes [PDF]
Physical Review Letters, 2019 We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas. Unlike current experiments, which repair the mismatch between axion and photon masses by breaking translational invariance (cavity and dielectric haloscopes), a plasma haloscope enables resonant conversion by matching the axion mass to a plasma frequency.

Tunable Nanoplasmonic Photodetectors
Nano Letters, 2022 Visible and infrared photons can be detected with a broadband response via the internal photoeffect. By using plasmonic nanostructures, i.e. nanoantennas, wavelength selectivity can be introduced to such detectors through geometry-dependent resonances.

Acta Crystallographica Section A Foundations of Crystallography, 2001 Investigation of the selectivity of a diol organic host for mixtures of DMF and DMSO, showed the formation of five inclusion compounds in which the stoichiometry varies in discrete steps and is determined by the composition of the liquid guest mixture; the structures of these compounds are described.

Spin-Polarized Tunable Photocurrents [PDF]
Nano Letters, 2021 Harnessing the unique features of topological materials for the development of a new generation of topological based devices is a challenge of paramount importance. Using Floquet scattering theory combined with atomistic models we study the interplay between laser illumination, spin and topology in a two-dimensional material with spin-orbit coupling ...

Tunable sieving of ions using graphene oxide membranes. [PDF]
Nature Nanotechnology, 2017 Graphene oxide membranes show exceptional molecular permeation properties, with promise for many applications. However, their use in ion sieving and desalination technologies is limited by a permeation cutoff of ∼9 Å (ref.

Recent Advances in Tunable Metasurfaces: Materials, Design, and Applications. [PDF]
ACS Nano, 2022 Metasurfaces, a two-dimensional (2D) form of metamaterials constituted by planar meta-atoms, exhibit exotic abilities to tailor electromagnetic (EM) waves freely. Over the past decade, tremendous efforts have been made to develop various active materials

High-sensitivity distributed dynamic strain sensing by combining Rayleigh and Brillouin scattering
Opto-Electronic Advances, 2020 The phase-sensitive optical time-domain reflectometry (φ-OTDR) is a good candidate for distributed dynamic strain sensing, due to its high sensitivity and fast measurement, which has already been widely used in intrusion monitoring, geophysical ...

Research of Distance-Intensity Imaging Algorithm for Pulsed LiDAR Based on Pulse Width Correction
Remote Sensing, 2022 Walking error has been problematic for pulsed LiDAR based on a single threshold comparator. Traditionally, walk error must be suppressed by some time discrimination methods with extremely complex electronic circuits and high costs.
