Microgrippers are typical MEMS devices used to pick, hold and transport micro-objects. Microgrippers are widely used in the field of micro-assembly, micro-surgery and manipulation of micro-particles. Thermal microgrippers are widely used for large displacement, high accuracy and ... Per saperne di più
The silicon cantilever with the planar coil was applied to the magnetic flux density measurements. The influence of shape and dimensions of planar coil on magnetic energy density was described. In cause of magnetic anisotropy of analyzed silicon structure FEM method and couple field ... Per saperne di più
In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the ... Per saperne di più
The design of a magnetic resonance imaging (MRI) RF coil using finite element method-based analysis is an essential part of a multi-year research project at the National Institute of Standards and Technology, Gaithersburg, Maryland, where the goal of the project is to develop a “phantom” ...

In this paper we present a summary of our work on numerical modeling of superconductors with COMSOL Multiphysics®. We discuss the two models we utilized for this purpose: a 2-D model based on solving Maxwell equations and a 1-D model for thin conductors based on solving the integral ... Per saperne di più
Steam generators (SGs) are used in CANDU® nuclear reactors as heat exchangers to convert water into steam using heat generated in the reactor core. Ferrous trefoil broach support structures prevent excessive vibration of thousands of SG tubes. A probe that uses pulsed eddy current (PEC) ... Per saperne di più
微波作为信息和能量的载体具有同等重要的应用价值，利用微波对物质产生的物理化学效应进行能量传递及转换已经在化学领域有了积极的应用。从 1986 年 R.N. Gedye 等人首次使用微波促进化学反应使其反应速率提高 1240 倍以来，有越来越多的微波和化学领域的科学家对相关问题进行了研究，并出现了一门新兴学科“微波化学”。微波化学作为研究微波能的一个方面是研究微波与化学反应体系相互作用的一个新兴学科。由于当前人们对微波加快化学反应的研究还非常肤浅，微波在大规模应用中并未发挥出其应有的巨大优势，微波化学进一步发展面临着巨大的挑战和机遇 ... Per saperne di più
We demonstrate the use of COMSOL Multiphysics with MATLAB to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and ... Per saperne di più
Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML ... Per saperne di più
Linear wave propagation through inhomogeneous structures of size R?? (Fig.1) is a computationally challenging problem, in particular when using finite element methods, due to the steep increase of the number of degrees of freedom as a function of R/?. Fortunately, when the geometry of ... Per saperne di più
