Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. Such enhanced local fields have many applications such as ... Read More
Numerical Modelling of a Free-Burning Arc in Argon. A Tool for Understanding the Optical Mirage Effect in a TIG Welding Device
In this paper, we present the numerical modelling of a free-burning arc and its application to the understanding of optical mirage effect which could occur in a TIG (Tungsten Inert Gas) device used in welding applications. Read More
Modeling of a DBD Reactor for the Treatment of VOC
Non-thermal plasma, generated in atmospheric pressure discharges, has been investigated in our laboratory in order to treat highly diluted (300 ppm to 1000 ppm) volatile pollutant. The collision of electrons created in the discharge with atmospheric air, leads to the formation of ... Read More
Understanding “Mutual Inductance” using COMSOL Multiphysics®
A teaching platform that could be used to help students understand concepts such as; flux linking and mutual inductance has been developed using the AC/DC Module of COMSOL Multiphysics®. This is achieved through the accurate determination of different magnetic flux density components ... Read More

Negative Ion Beams and Secondary Beams
The development of powerful negative ion sources requires precise and versatile simulation tools to predict the emittance of the extracted ion beams and the heat load on the electrodes. A first tool is a determination of the plasma beam interface which is accomplished by a set of macro ... Read More
A Magnetohydrodynamic Study of a Inductive MHD Generator
The aim of the proposed device is to overcome the typical drawbacks of MHD generators, such as the needed of a very high external magnetic field, the strong dependency of the efficiency by the temperature of the fluid, and the deterioration of the electrodes that are in contact with the ...

3D Modeling of Microwave Plasma Using Funer Model
After previous microwave simulations done with very hard assumptions, we improve the model by using Funer model to improve prediction of plasma effects on the microwave coupling. Some parameters are still not well known and are used as adaptation parameters. An experience plan technique ... Read More
