The detection and identification of the location of a sound source is commonly done using arrays of microphones. A recent new alternative approach has been proposed which involves the use of continuous structures, such as beams or plates, as acoustic wave sensors. The sound wave impinging on the surface of the structure causes it to vibrate and the measured surface displacements can then be used ...

This paper will give a short overview of use of COMSOL Multiphysics for analyzing ancient Greek and Roman catapults with the main focus on the energy storing torsion springs. Catapults have been known and used in the Greek and Roman world from around 399 BC and a fully standardized design for powerful torsion catapults emerged around 270 BC, based on one basic factor, the diameter of the torsion ...

In this paper, we use a COMSOL Multiphysics® model to demonstrate the potential use of polymer microring resonator structures for optical biosensing applications. When the refractive index of the area surrounding the microring resonator changes, there is a shift in the resonance wavelength that can be monitored. We present simulated results of the spectral response with different refractive ...

Standard approaches to reproduce the coupling of wave propagation and plasma transport inside a helicon plasma source rely on electromagnetic simulations coupled to either kinetic or particle-in-cell strategies to reproduce the plasma response. If the plasma density reach values higher than 10^17 m^-3, these approaches would result in a computational burden, therefore we have adopted a fluid ...
