Outline of presentation: In electromagnetic technology applications the finite element method is very well suited for a wide range of problem types For many cases, in particular when inhomogeneous materials having complex properties are involved as well as when multiphysics couplings ... 詳細を見る

The recently developed technique Scanning Tunneling Microscopy in the Field Emission regime (STM FE) is based on the Russell Young's topografiner technology. The set-up is a no contacting device consisting of a sharp tip approached vertically to a conducting surface at variable distances ... 詳細を見る

A 3D model of a magnetic rotor both rotating and translationally moving at high-speed over a conductive guideway is modeled in steady-state using the convective A*-Φ formulation. The presence of the magnetic rotor (source field) is incorporated into the formulation via the boundary ... 詳細を見る

The application of nanoparticles coupled with medical agents to brain tumors remains one of the biggest obstacles in neuro scientific research. This work explores an optimal design of an electromagnet to overcome the blood-brain barrier by means of an intensive external magnetic field ... 詳細を見る

This paper presents the mathematical modeling for the analysis of the magnetostrictive materials, which describes the behaviour of the magneto-mechanical coupling in a rod of magnetostrictive material and capturing it in COMSOL® to produce a predictive and detailed analysis. A simulation ... 詳細を見る

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 ... 詳細を見る

Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... 詳細を見る

Large deflection actuators are becoming increasingly important for microsystems. Since actuation forces are usually small, large deflection actuators usually require flexures with low stiffness. Rectangular serpentine flexures are often used for such actuators due to their low stiffness ... 詳細を見る

Penning-trap mass spectrometers are the tools of choice for mass-ratio measurements of two different single ions with highest precision. The investigated ions are stored consecutively in a combination of an electric quadrupole potential and a homogeneous magnetic field at ultra-high ... 詳細を見る

This work is concerned with the study of the asymmetrical phenomenon observed in three-phase transformers during the standard short-circuit test. The purpose of our work is to see if the asymmetric measurements can be predicted with the use of 2D finite-element models. To this end, we ... 詳細を見る
