The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at ... En savoir plus

We report an implementation of parallel computing on Amazon Web Services™ (AWS) for touch-sensor modeling. COMSOL Multiphysics® was used to simulate an electromagnetic field distribution in a capacitive sensor assembly. Multiple COMSOL jobs were deployed on separate AWS instances and ... En savoir plus

Metamaterials and metasurfaces are emerging technologies in the field of nanophotonics. They can enable the engineering of arbitrary optical response based on their nano structure. The desired effective optical response is quantified by amplitude and phase of the light reflected and ... En savoir plus

EDF Energy use an Eddy Current Inspection Tool (ECIT) to test the properties of graphite bricks in the cores of UK Advanced Gas-cooled Reactors (AGRs). The tool comprises a coil containing an alternating current which generates a magnetic field, inducing eddy currents within the nearby ... En savoir plus

In this contribution, we simulate the optical response of piezoelectric planar optical microcavities (POMCs) under the modulation introduced by a propagating surface acoustic wave (SAW). The physical picture of the model is shown in Figure 1. A metallic interdigital transducer (IDT) is ... En savoir plus

New methods of generating high-frequency magnetic fields of tens or even hundreds of millitesla at frequencies exceeding 2 MHz are allowing important new applications for induction heating. These include heating low conductivity ionic solutions in situations where electric or ... En savoir plus

The acceleration of protons and ions by highly intense, ultra-short laser pulses is a very active field of experimental and theoretical research. From laser-plasma interactions the emission of a strong electromagnetic pulse (EMP) has often been reported as a side effect. It potentially ... En savoir plus

A tapered cylindrical microwave resonant cavity, a frustum, also commonly known as an EM Drive, has been reported to produce thrust by the generation of EM radiation within a resonant cavity without using any propellants. In order to determine how a sealed microwave cavity can produce ... En savoir plus

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also ... En savoir plus

Localized Joule heating within integrated circuit (IC) chips is the leading cause of non-uniform temperature distribution within the circuit structure of the chips. Such variation in temperature enhances the biased diffusion of metal atoms along current carrying interconnects, a ... En savoir plus
