A photoelectrochemical (PEC) cell uses solar energy to split water to hydrogen and oxygen in single integrated device. Electrochemical impedance spectroscopy is a suitable tool to characterize recombination and reaction mechanisms in PEC cell. Full numerical drift-diffusion calculations ... En savoir plus
Accurate modeling of magnetostrictive materials and devices requires coupling of electrical, magnetic, mechanical, and possibly acoustic domains. There are relatively few finite element software packages that include all these physical models and even fewer that include magnetostrictive ... En savoir plus
Estimation of both single-ended (SE) and differential-pair (DP) impedances of high-speed PCB-traces/interconnects, vias and connectors is very important for the high-speed PCB (layout) design. This is because, the mismatch in line-impedances/improper line-termination results in a ... En savoir plus
The underwater electric potential (UEP) signature of naval vessels poses a severe threat as it is detectable by advanced sea mines. The signature depends also on the environment, mainly the water-seabed interface, leading in summary to the total UEP signature. The seabed has a ... En savoir plus
In the humanitarian demining setting, it is crucial to detect landmines with reliable sensing performance. As Nuclear Quadrupole Resonance (NQR) is an effective method for detecting explosive materials, our group is currently developing the world’s first low-cost system for anti-vehicle ... En savoir plus
In the context of non-destructive evaluation methods, eddy-current testing plays a prominent role in crack-detection problems, due to its various attractive features. One of the physical quantities that typically interest us in such type of problems is the – complex – coil impedance and ... En savoir plus
One of the advantages of microwave heating of a dielectric material is the direct transfer of electromagnetic energy to the core of the dielectric through interactions between electromagnetic waves and the dielectric, without heating the surrounding elements [1]. For an industrial ... En savoir plus
In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training ... En savoir plus
Ultrasound Imaging probes are specific devices that require a very detailed design of acoustic impedance match for the stack of layers that form the probe head (1,3). These are typically made of silicone rubber, special epoxy resins, polyurethanes and, of course, piezoelectric ... En savoir plus
The main purpose of a drive unit is to transform the electrical signal at its terminals into acoustic waves via two transduction mechanisms: electro-mechanical and mechano-acoustical. In this paper only the electro-mechanical transformation is discussed in view of a future optimization ... En savoir plus
