Terahertz Quarter Wave-Plate Metasurface Polarizer Based on Arrays of Graphene Ribbons

We propose a novel graphene-dielectric-based meta-surface for manipulating the polarization of the incident light in the terahertz regime. The proposed structure comprised two orthogonally oriented periodic array of graphene ribbons (PAGRs) which are separ ...

Design of Full-Metal Polarizing Screen Based on Circuit Modeling

Maria Garcia Vigueras

A polarizing sheet based on a fully metallic structure is here reported for the first time. The polarizer consists of a doubly-periodic arrangement of squared-wave guide sections enclosed by two perforated screens. Though the waveguide sections are highly ...

Charge screening strategy for domain pattern control in nano-scale ferroelectric systems

Nava Setter, Tomas Sluka

Strain engineering is a widespread strategy used to enhance performance of devices based on semiconductor thin films. In ferroelectrics strain engineering is used to control the domain pattern: When an epitaxial film is biaxially compressed, e.g. due to la ...

Twisting Fluorescence through Extrinsic Chiral Antennas

Olivier Martin, Chen Yan, Xiaolong Wang

Plasmonic antennas and planar structures have been undergoing intensive developments in order to control the scattering and absorption of light. One specific class, extrinsic chiral surfaces, that does not possess 2-fold rotational symmetry exhibits strong ...

Selective Probing of Hidden Spin-Polarized States in Inversion-Symmetric Bulk MoS2

Jan Hugo Dil, Joël Mesot, Stefan Peter Muff, Andrea Pisoni, Mauro Fanciulli, Elia Razzoli, Philipp Aebi

Spin-and angle-resolved photoemission spectroscopy is used to reveal that a large spin polarization is observable in the bulk centrosymmetric transition metal dichalcogenide MoS2. It is found that the measured spin polarization can be reversed by changing ...

Wideband Omnidirectional Planar Antenna with Vertical Polarization

Juan Ramon Mosig, Lei Wang

In this paper we propose a circular leaky wave-antenna with omnidirectional radiation in the H-plane. The design utilizes double-layered strips to create an end-fire antenna. A linear tapering of the stripes in the design endows the antenna with a 27% impe ...

Measuring Nano- to Microstructures from Relayed Dynamic Nuclear Polarization NMR

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli, Arthur César Pinon, Pierrick Berruyer, Etienne Christophe Socie, Judith Schlagnitweit

We show how dynamic nuclear polarization (DNP) NMR can be used in combination with models for polarization dynamics to determine the domain sizes in complex materials. By selectively doping a source component with radicals and leaving the target undoped, w ...
