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 ...

Electrokinetic (EK) techniques have been broadly implemented in a variety of fields, including microfluidics and lab-on-a-chip, and are seeing increased interest to miniaturize and optimize fluid pumping and mixing systems. While EK techniques such as electro-osmosis and ... En savoir plus

Introduction: The use of microwave energy for thermal cracking (from thermal stress and water pore pressure) of lignite-coal briquettes increases the lignite friability [1] and is beneficial for later chemical treatment inside a gasifier (for methanol production for example). An ... En savoir plus

Seawater can be converted into fresh water using solar energy. This is as an easy, suitable and green solution method to obtain heat for desalination. It is possible to concentrate the sunlight heat flux onto a small focal area by using a Fresnel lens. When the focal area is correctly ... En savoir plus

The use of plasmonic effects to dramatically enhance the electromagnetic field near the surface of a metallic nanostructured surface has grown into a large research area in the effort to take advantage of the surface enhanced field. In this paper the electromagnetic field near a nano ... En savoir plus

Most probably Gauss\'s law is considered as the first \"electromagnetic\" concept for early undergraduate physics and electromagnetic courses. In early study year, teaching Gauss’s law is usually performed based on two main components; 1) The use of simple symmetrical charge ... En savoir plus

The axial injection torch (AIT) produces high-density plasmas by coupling microwave power to a flowing gas. The plasma is imposed by defining its electron density and temperature whose maximum are given by optical emission spectroscopy diagnostics. Our study of an AIT with COMSOL ... En savoir plus

The extraordinary electromagnetic response of nanostructured material, usually made up of a metallic structures distributed in within a dielectric matrix has attracted a lot of interest in recent years. These materials are technically called metamaterial (MM) since they possess ... En savoir plus

Introduction The monitoring of bacteria concentration in drain fluid is the most common way to estimate the success of a colon surgery. However, the lack of efficient method to follow the development of E.coli in drain fluid after surgery is often fatal to the patient. The proposed ... En savoir plus

Fluid flow has the potential to provide significant mechanical energy input for electromagnetic energy harvesters. The effect of a bluff body, such as cylinder played a significant role in the creation of a Karman vortex profile in the fluid flow. We study the effect of the number and ... En savoir plus
