Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... Read More
COMSOL Multiphysics has been applied to develop a model for inductive heating. A coarse, lumped model of the interior of a high temperature reactor is coupled to finite element models for the electromagnetic field, the temperature distribution outside the reactor, and mechanical stresses ...

This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... Read More
Due to the inseparability of the wave equation, numerical methods are needed to develop an accurate electromagnetic model for various axisymmetric resonators such as micro-discs and micro-toroids. Our purpose is the implementation of a perfectly matched layer to determine the quality ... Read More
We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered ... Read More
Designing a Radio Frequency (RF) birdcage coil used in Magnetic Resonance Imaging (MRI) at high frequencies where the wavelength is comparable with the coil dimensions is a challenging task. Before construction of the coil, not only calculating the capacitance value which is necessary ... Read More
