本文利用COMSOL软件仿真了有限宽度的平行黑磷对的等离子体传输及模态分布性质，其中包括它们的光限比和梯度力。首先，设置了两个黑磷层之间的三种不同的相对取向。由于黑磷在光学性质上表现出强烈的各向异性，在三种情况中都发现了对称和反对称模式的存在。对称模式下的电场主要集中在两层黑磷之间，而反对称模式下的电场更多的分散在黑磷对的两侧。结果表明，与反对称模式相比，对称模式表现出更大的光限比和梯度力。更有趣的是，发现zigzag-zigzag结构具有最大的梯度力，而armchair-zigzag结构具有最大的光限比。当两个黑磷层分别沿armchair和zigzag方向时 ...

Introduction With the vast development in the aerospace industry it is inevitable that currently used materials such as Nickel based super alloys will soon reach its peak performance. Hence developing alternative materials with similar properties that could be enhanced further is ... En savoir plus
MEMS resonators have been recently adopted in a wide variety of timing, sensing, and actuation applications. The ability to control the dynamics of resonance, namely the resonance frequency and quality factor of these resonators is crucial in achieving high precision performance within ... En savoir plus
It is possible to control the motion of magnetic beads using a combination of hydrodynamic and electromagnetic forces. In this work, we investigate the possibility to manipulate the motion of beads with different magnetic moments in a special microfluidic structure so as to separate ... En savoir plus
Dedicated work in modeling, simulation and design optimization of Lithium-ion Battery (LIBs) was done in the past decades, and still, the most widely used one for electrochemical processes is the Newman model. [1] The underlying parameters are treated deterministically, but the impact of ... En savoir plus
Finite element modelling of electrical machines usually assumes uniform magnetic properties and loss behaviour throughout the steel laminations. It is well known that manufacturing processes, like the assembly of the machine, deteriorate the properties of the core material. Generally, ... En savoir plus
A portable device that can identify protein and peptides real time in complex biological systems such as human bodily fluids reliably and accurately is in high demand to properly diagnose and treat medical conditions. Lynntech has developed an innovative Polydimethylsiloxane (PDMS) based ... En savoir plus
In this work we investigate a wet-chemical silicon etching process. COMSOL Multiphysics® is used to extract local pressure values to correlate them to experimental results. The test setup consists of a box with a fixed wafer and a nozzle that injects an etchant jet onto the wafer ... En savoir plus
In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... En savoir plus
The optical fiber communication has been popular topics besides robot study nowadays. In the process of the Dense Wave-Length Division Multiplexing (DWDM) study, the dispersion compensate for the traditional optical fiber is difficult to solve for long distance transport information. It ... En savoir plus
