Understanding the Magnetic Field Penetration in Mesoscopic Superconductors via COMSOL Multiphysics® Software

I. G. de Oliveira[1]
[1]Universidade Federal Rural do Rio de Janeiro, Seropédica, RJ, Brazil

Introduction: One of the main characteristic of the superconductors is its diamagnetic response of applied magnetic fields. The superconductors refuse the penetration of magnetic field into its interior, it is the well know Meissner effect, B=0 into the superconductor sample. However ... En savoir plus

Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording

J. Bennington[1]
[1]Queen's University Belfast, Belfast, Northern Ireland, UK

A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... En savoir plus

Design and Simulation of an Orbiting Piezoelectric MEMS Gyroscope Based on Detection of Phase-Shift Signals

S. Gorelick[1], J. R. Dekker[1], B. Guo[1], H. Rimminen[1]
[1] VTT Technical Research Centre of Finland, Espoo, Finland

The feasibility of phase-sensitive detection of angular-rates using bi-directional orbiting piezoresonators suspended by thick annular springs with thin-film aluminium nitride piezoactuators on top of them was investigated. The ring-shaped flexures are more suitable for supporting the ... En savoir plus

Optimization of the Slot Dimensions of a Large Air-gap Linear Synchronous Motor

F. Giacometti[1], C. R. Lines[1], R. J. Cruise[1]
[1]Texchange Limited, London, UK

A COMSOL Multiphysics® model is used to optimise the slot geometry of a large air-gap linear synchronous motor. Fixed dimensions are used for the pole pitch, stator depth, stator width and air-gap, since the amount of available space is usually limited. A parametric sweep of the slot ... En savoir plus

Web-Based 3D Visualization for COMSOL Multiphysics® Software
