Eddy current thermography (ECT) is a non-destructive contact-free method of defect detection in a conductive material combining the electromagnetic induction of eddy currents and thermal imaging. This technique uses an excitation system consisting of an inductor with coil(s) carrying ... En savoir plus
In this work, a 2.8x0.22 μm^2 silicon strip waveguide (n = 3.43 @4.234 μm) on a silica substrate (n = 1.38 @4.234 μm) and a superstrate with n = 1 was designed and evaluated through 2D (i.e., mode analysis), and 3D (i.e., wave propagation) analysis to strengthen the interaction between ...

The contamination of food products with low water contents is a safety issue that cannot be disregarded. Despite their low water activity, they are indeed susceptible to infection by micro-organisms that are highly resistant to heat. In this case, conventional pasteurisation techniques ...

Quasi-static 2D-MEMS vector scanners are micro-opto-electro-mechanical systems (MOEMS) made of monocrystalline silicon. The primary application for these controllable micromirrors is the high dynamic and precise deflection of laser beams, for example in light detection and ranging ... En savoir plus
This paper presents numerical simulation of plate wave modes in thin stainless steel plates using a racetrack spiral coil electromagnetic acoustic transducer (EMAT), which works under the principle of acousto-elastic effect, called Lorentz force mechanism. EMATs are useful for non ... En savoir plus
The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, a new quasi-TEM capacitance and inductance analysis ... En savoir plus
In this paper an Electromagnetic Solenoid Actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) systems for internal combustion engines. The analysis of ... En savoir plus
The application of an oscillating magnetic field on the high-power full-penetration laser beam welding process of a 20 mm thick stainless steel plate was numerically and experimentally investigated. In the simulations, three-dimensional heat transfer and fluid dynamics as well as ... En savoir plus
Current transformers are used to measure currents in power grid systems. They are characterized by strong interactions between external electrical sources and loads respectively and the magnetic subsystem. Self-heating due to losses has to be considered because of the temperature ... En savoir plus
This paper presents a snap shot of experimental work, which has been conducted at NTNU on billet heating with induction coils. A significant volume of experimental data have been collected for coils running with up to 0.2T: high accuracy Hall probe readings (+/-1%), metal ... En savoir plus
