Study of Electromagnetic Shielding, a Comparison between Experiment and FEM Simulation

G. Sun [1], C. De Blasiis [1], O. Sekula [1], P. Corsaro [1],
[1] Brugg Kabel AG, Brugg, Switzerland

The loaded underground high voltage cable generates magnetic field with industrial frequency. Depending on the current rating and cable allocation, the magnetic exposure to public area may exceed the requested limit from customer. Extra shielding should then be applied. A primary FEM ... 詳細を見る

[1] Department of Electronic Engineering, Universitat Politècnica de València, Valencia, Spain
[2] Instituto Universitario de Matemática Pura y Aplicada, Universitat Politècnica de València, Valencia, Spain

Radiofrequency ablation is one of the common methods used to treat pain, movement or mood disorders. It bases on the electromagnetic energy provided to the selected tissue when an alternating current is applied. The resistive heating produced in this process provokes temperature rise in ... 詳細を見る

Predicting Degradation of a Composite Material Due to an Injected Current

J. Rivenc [1],
[1] Airbus Group Innovations, Toulouse Cedex, France

The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... 詳細を見る

[3] Karlsruhe Institute of Technology (KIT, IHM, IHE), Karlsruhe, Germany

The lamination of substrates with thin coatings is commonly used in furniture, automotive and avionic industries. In the lamination process the hot melt adhesives are widely used and typically activated at temperatures from 80°C to 140°C by resistive heating. This requires a heat ... 詳細を見る

Structural Design of a NFC-Reader-Antenna for Automotive Electronics with FEM Simulation

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH, ZF-Friedrichshafen AG. Group, Friedrichshafen, Germany

The design of a right contour/structure of the NFC-antenna is presented. The NFC-reader-antenna is applied later to communicate with the NFC-tag (transponder) of a smart phone placed in the phone box of the car. The NFC-reader-antenna with selected contour is printed directly on the PCB ... 詳細を見る

A 2D Model of a DC Plasma Torch

B. Chine' [1],
[1] School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica

Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the ... 詳細を見る

Simulation of an Electromagnetic Sheet Shearing System

Y. Huang [1], X. Li [1], Q. Xiong [1], Z. Lai [1], Q. Cao [1], L. Li [1],
[1] Wuhan National High Magnetic Field Center, Huazhong University of Science and Technology, Wuhan, Hubei, China

Electromagnetic shearing (EMS) is a high speed sheet metal shearing system where the workpiece is fractured under a pulsed electromagnetic force. It can be regarded as an extension of electromagnetic forming[1-2]. The basic shearing principle is that a huge repulsive electromagnetic ... 詳細を見る

[1] Northwest A&F University, Yangling, Shaanxi, China

A computer simulation model was developed using finite element-based commercial software, COMSOL Multiphysics®, to simulate temperature distributions in wheat samples packed in a rectangular plastic container and treated in a 6 kW, 27.12 MHz RF system with and without mixing conditions. ... 詳細を見る

Asymmetry Induced Terminal Voltage Improvement in Mg2Si-based Thermoelectric Unicouple

P. Priyadarshi [1], J. Bahl [1], B. Muralidharan [1]
[1] Indian Institute of Technology Bombay, Mumbai, India

Thermoelectric power generation has been envisioned as a clean energy alternative to conventional thermal to electric power generation for decades due to its noiseless and low-cost operation. However, a typical thermoelectric generator suffers from low device efficiency, so it has been a ... 詳細を見る
