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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
