Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... En savoir plus
Modeling the effects of electromagnetic fields on biological structures on the order of the body and tissues to the micro (1e-6)-and nano (1e-9) level of cells and sub-cellular structures presents formidable challenges. We share the major lessons we have learned using COMSOL ... En savoir plus
The state of the art technology is moving towards more complex and multidisciplinary processes and systems. There is a growing interest in using Multi-physics simulations to have a better understating of the underpinning science of the processes as well as providing cost-effective ... En savoir plus
Induction heating is used in lot of applications: forging, brazing, hardening, melting, bonding. The main advantage is ability to heat quickly, efficiently, and locally with a good repeatability. It leads to productivity and energy efficiency improvement. These solutions are often used ... En savoir plus
The Multiphysics design of a 130 GHz klystron Buncher cavity is described in this paper. In this high frequency range, dimensions are critical and expose the device to multiple physics effects, due to the power dissipations, affecting the electromagnetic performances. The proposed device ... En savoir plus
Fusion devices (tokamaks, stellarators) require hundreds of millions degree Celsius temperature to reach the plasma state when the fusion reactions start to occur. Ion cyclotron resonance heating (ICRH) is a method of energy transfer to the ions in the plasma from electromagnetic ... En savoir plus
Superconducting Magnet system have great application at places which require high magnetic fields, such as the accelerator systems, Magnetic Resonance Imaging and Mag Lev systems to name a few. The superconducting state exists at cryogenic temperature and it is defined by its critical ... En savoir plus
The purpose of this paper is to illustrate the microwave coagulation therapy (MCT) that can be used mainly for the treatment of hepatocellular carcinoma. In this treatment invasive technique are used in which thin microwave coaxial antenna is inserted into the tumor and the microwave ... En savoir plus
Auto assembled Ag-ZnO [1] star shaped nanostructures depicted in figure 1, presents their natural electromagnetic resonance at 60 THz. In this work we present that is possible to change this value by covering it with a variable in thickness layer of gold. The analysis is performed by ... En savoir plus
The objective is to analyze temperature rise and distribution in different parts of an inductive brazing process. This process includes multiphysics phenomena - electromagnetic excitation- eddy heating- heat transfer in solids. AC Inductive heating physics coupled to heat transfer in ... En savoir plus
