Graphene-based metasurface sensing applications in terahertz band

Results in Physics, 2021
Ultra-high sensitivity sensor has significant application for micro-nano optical devices in terahertz. Here, we propose a simple graphene metasurface, which can achieve obvious graphene plasmon-induced transparency (PIT) phenomenon. We can find that PIT,

Slow-light plasmonic metamaterial based on dressed-state analog of electromagnetically-induced transparency

, 2015
We consider a simple configuration for realizing one-dimensional slow-light metamaterials with large bandwidth-delay products using stub-shaped Fabry-Perot resonators as building blocks.

Active Control of Electromagnetically Induced Transparency Analogy in Spoof Surface Plasmon Polariton Waveguide

Photonics, 2022
Metamaterial analogues of electromagnetically induced transparency (EIT) enable a unique avenue to endow a coupled resonator system with quantum interference behavior, exhibiting remarkable properties in slow-wave and highly sensitive sensing.

Plasmon-induced transparency effect of flexible terahertz metasurface

上海师范大学学报. 自然科学版
In recent years, the terahertz micro/nano-photonics research group of Shanghai Normal University has carried out a series of research work on the terahertz (THz) plasmon-induced transparency (PIT) using planar metamaterials, which attract highly ...

Influence of the Rashba effect on the Josephson current through a superconductor/Luttinger liquid/superconductor tunnel junction

, 2004
The Josephson current through a 1D quantum wire with Rashba spin-orbit and electron-electron interactions is calculated. We show that the interplay of Rashba and Zeeman interactions gives rise to a supercurrent through the 1D conductor that is anomalous ...

Ultra-high field enhancing in Split Ring Resonators by azimuthally polarized excitation

, 2011
We study the field enhancement and resonance frequencies in split-ring resonators (SRR) illuminated by azimuthally polarized light. We find that compared to linearly polarized illumination, the azimuthally polarized illumination increase the intensity ...

Geometry-symmetry-free and material-symmetry-guaranteed polariton-induced transparency

iScience
Summary: Plasmon-induced transparency is a classical analogue of electromagnetically induced transparency (EIT). However, its realization and control primarily rely on geometry engineering rather than tuning plasmon polaritons (PPs) themselves, due to ...

Direct dark mode excitation by symmetry matching of a single-particle based metasurface

, 2014
This paper makes evidence for direct dark mode excitation mechanism in a metasurface structure. The dark mode excitation mechanism is entirely determined by structures' symmetry and does not depend on near-field coupling between elements. In our examples,
