Splitting a 3D model into two coupled components can increase performance [1]. Two offshore applications with the AC/DC module and the heat transfer module are presented, but the approach is general. The examples simulate the hotspot temperature in a three core cable with cross-sectional ... En savoir plus

Particle In Cell (PIC) simulation tool for the simulation of 2.45GHz ECR ion source was developed tanks to Comsol Multiphysics RF module capability to compute electromagnetic field propagation imposing a tensorial permittivity with real and complex parts. A tensorial description is ... En savoir plus

X-rays represent high-energy electromagnetic radiation capable to penetrate matter and are therefore widely used in medical diagnostics, material testing and various other applications. They are typically produced by vacuum tubes with electrons emitted from a hot cathode and accelerated ... En savoir plus

The current general context for green production and decarbonation prompts considering alternative solutions to produce high added value byproducts from gas decomposition without producing CO2. Steam Reforming or Combustion processes, widely applied in Industry, need H2O or O2 to ... En savoir plus

Klein tunneling is one of the most striking consequences of Dirac equation. Despite experimental investigations of the phenomenon in analog systems in the transport or quasi-bound state scenario, a direct observation of quantized Klein tunneling is still lacking. Now this is achieved in ... En savoir plus

The high-temperature superconducting magnet (HTS) is one of the core technologies of a superconducting maglev. The effects of multiphysics fields including electromagnetic, mechanical, and thermal should be taken into consideration in design. Traditional design methods rely on the ... En savoir plus

Magnetic Resonance Imaging (MRI) is a powerful tool for exploring brain function, offering detailed insights into its structure and physiology. Combining MRI technology with electrophysiological recording systems can enhance comprehension of brain functionality through synergistic ... En savoir plus

The integrity and safety of reinforced concrete structures are of paramount importance in civil engineering. Detection of flaws in prestressed tendons, especially those buried at critical depths greater than 20 cm, presents a significant challenge. Magnetic flux leakage (MFL) is a non ... En savoir plus

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 ...
