This paper describes the design of a normally closed, electrodynamic microvalve. Magnetic forces between a permanent magnet in the valve cover and a soft magnet in the valve seat hold the valve closed. The combination of electrodynamic actuation and a mechanical restoring spring are ... 詳細を見る
Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous ... 詳細を見る
The most popular means of depression treatment are psychotherapy, antidepressant medication and recently adopted transcranial magnetic stimulation (TMS) of the human brain. To overcome their disadvantages we are investigating an application of low-field magnetic stimulation (LFMS) to ... 詳細を見る
Marco Cati graduated cum laude and encomium citation in electronic engineering in 2001 from the University of Florence, where in 2005 he also received a Ph. D. degree in electronic engineering. In 2005 he joined the Research & Development Department of Esaote where he is currently in ... 詳細を見る
在微波加热的多物理场仿真中，如果被加热物体的几何区域太小或者太薄，会造成整个模型网格剖分困难、网格数量多且计算消耗内存大等问题。本文针对微波加热时薄壁容器的网格剖分困难，网格数量大，且占用计算机内存资源多的问题，提出了一种基于变换光学算法的微波薄壁加热模型计算优化方法。利用变换光学算法将薄壁区域空间扩大，通过改变薄壁区域内的介质参数来与原模型进行空间映射，从而避免网格剖分过程中的薄壁问题出现，这样可以在同样的网格剖分设置下减少整个模型的网格数量，节省计算时间，减少计算机内存资源的占用。通过相应的公式推导，在二维模型中实现了薄壁变换光学算法的计算 ... 詳細を見る
Surface Enhanced Raman Scattering (SERS) phenomenon is well known for its detection sensitivity, however, to better understand how it works a better insight needs to be developed on the physics behind the phenomenon. The physical aspects known to produce SERS effect are the use of ... 詳細を見る
Harald Biller studied mathematics and physics at Darmstadt, London, and Würzburg. In 1999, he received his PhD from Stuttgart University, specializing in functional analysis, topology, and Lie theory. He worked as a lecturer at Darmstadt University until 2004, when he became a ... 詳細を見る
It has already been demonstrated that fluid models can be used to simulate two-dimensional axisymmetric inductively coupled plasma via implementation in the COMSOL (multi-physics simulation software) platform. In this study, we improved the model and simulated a large scale magnetized ... 詳細を見る
The aim of this study is to compare the diffraction efficiency of a sinusoidal diffraction grating numerically calculated using COMSOL Multiphysics® with the measured results performed with a custom-made equipment and calculations using Bessel functions. A diffraction grating with the ... 詳細を見る
The majority of electrical machines are designed to produce the rotary motion, there by exploiting the blessing of circularity which man has enjoyed since the discovery of the wheel. Electromagnetic forces may also be employed to produce the linear motion resulting in linear motion ... 詳細を見る
