The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these changes. The method is based on the creation of a primary magnetic field that will produce eddy currents in the ...

Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis (based on mathematical formulas) can be uncertain. The applied FEM method of the analysis can be a solution to ...

This paper presents the quasi-TEM two-dimensional (2D) approach for the analysis of multiconductor transmission lines interconnect in single and two-layered dielectric region using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is as suitable and effective as other ...
Calibrating electric instruments of the Huygens probe and modelling the dielectric properties of the atmosphere and of the surface of titan
Centre d'Etude des Environnements Terrestre et Planétaires (CETP), Saint Maur des Fossès, France
In 14 January, 2005, the Huygens Probe has descent through the atmosphere of Titan and has survived to touchdown, collecting data in the atmosphere and on the surface of the largest moon of Saturn. One of the instruments, the Huygens Atmospheric Structure Instrument (HASI), includes the Permittivity, Waves, and Altimetry (PWA) analyser, which is a subsystem for studying the electric activity of ...

The pilot Molte lead-bismuth target circuit (TC-1) in the University of Nevada was designed for beam power of 1 MW accelerator driven system (ADS). Circulation of the liquid alloy is driven by an annular linear induction pump. A numerical study of the pump efficiency has been conducted to determine which operational parameters are responsible for this low efficiency and to give insight ...

A research team at FSU CAPS is developing a novel fast disconnect switch based on a piezoelectric actuator for use in next-gen electric power distribution systems. COMSOL Multiphysics® software was used to optimize geometry and material selection of the disconnect switch. Current conduction, mechanical stress, and electrostatic simulations were performed to confirm that design requirements of ...
