Superconducting coils are used to generate high magnetic fields in various applications such as nuclear fusion reactors, particle accelerators, actuators and MRI scanners. Electrodynamic modelling of superconductors is challenging because of the significant nonlinearity in the electric ... En savoir plus

Balanced armature (BA) micro-speakers, or receivers, are miniaturized loudspeakers used in hearing aid instruments, earphones, and hearables. A typical design of a BA receiver includes an armature (metal beam) with a coil wound around it. The armature tip is positioned exactly in the ... En savoir plus

This work presents a comprehensive modeling and validation study of MEMS-based infrared (IR) emitter chips using a neural network-assisted inverse modeling approach in COMSOL Multiphysics. Starting from a single baseline chip geometry, a simulation model was developed that captures the ... En savoir plus

Stray light represents a significant challenge in a wide range of photodiode and photodiode array applications, as it elevates the background signal, reduces detector sensitivity, and degrades the signal-to-noise ratio. Traditional approaches to mitigate stray light, such as blackening ... En savoir plus

With the Creation, roll-out, and maintenance of COMSOL Simulation apps, the role of simulation engineers and departments is expanding to include responsibilities similar to those of software developers. Within our department, we have undergone this transformation and will share the key ... En savoir plus

Quantum computers are extremely sensitive to external disturbances which cause them to lose their quantum states. Reliable operation of quantum computers therefore requires effective magnetic shielding to protect qubits from external magnetic fields. Quantum computers typically operate ... En savoir plus

In modern optical systems, such as those used in automotive cameras, aerospace sensors, and surveillance equipment, optical windows serve as protective layers while allowing light to pass through. These windows must maintain high transmittance and simultaneously preserve image quality. ... En savoir plus

High average power lasers with increased efficiency are a crucial development required for achieving inertial confinement fusion as a viable energy source. For high average power, the thermal management and its influence on laser beam quality strongly effect the final focusability on ... En savoir plus

High-voltage (HV) power cables are vital components of modern electrical infrastructure, enabling power transmission over long distances with lower environmental footprint compared to overhead lines, i.e., improved visual impact, better biodiversity aspects and minimal wildfire risk. ...
