Study of Electromagnetic Shielding, a Comparison between Experiment and FEM Simulation
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 ... Mehr lesen
Model of a Pulsed Radiofrequency Technique for Pain Relief
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 ...

Predicting Degradation of a Composite Material Due to an Injected Current
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. ... Mehr lesen
Model of Microwave-Assisted Thermal Adhesion of Synthetic Leather to a Plastic Substrate
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 ... Mehr lesen
Structural Design of a NFC-Reader-Antenna for Automotive Electronics with FEM Simulation
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 ... Mehr lesen
A 2D Model of a DC Plasma Torch
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 ... Mehr lesen
Simulation of an Electromagnetic Sheet Shearing System
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 ... Mehr lesen
3-Dimensional Numerical Modeling of Radio Frequency Selective Heating of Insects In Soybeans
Radio frequency (RF) heating have potential as alternatives to chemical fumigation for disinfesting legumes. This study was conducted to investigate the feasibility of RF selective heating of insect larvae in 3 kg soybeans packed in a rectangular plastic container using a 6 kW, 27.12 MHz ... Mehr lesen
A Strategy to Simulate Radio Frequency Heating Under Mixing Conditions
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. ...

Asymmetry Induced Terminal Voltage Improvement in Mg2Si-based Thermoelectric Unicouple
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 ... Mehr lesen
