Technical Papers and Presentations

The fabrication of piezo aluminium composite modules for sensor and actor applications with mass production technologies is in the scope of the SFB/Transregio 39 PT-PIESA project funded by the (German Research Foundation). After forming of cavities with a width of 0.3 mm into aluminium ... Read More

Silicon solar cells are produced in a series of different process steps in which wet-chemical etching and rinsing steps have a considerable influence on the quality of the wafers. Etching baths are used for surface structuring or intended etch back. Examples therefore are texturing, ... Read More

Noise reduction at low frequencies is a major issue in many workspaces and indoor public places. Unlike mid- and high-frequency noise, low frequency noise is less attenuated by using conventional sound absorbing materials. This communication proposes an electro-mechano-acoustic absorber ...

Outline of presentation: We have seen a few of the diverse ways e2v has started to use COMSOL It is allowing us to view our processes in a different way Resulting in improvements It is enabling our engineers and scientists to examine the full application, not just the microwave or RF ... Read More

A growing demand is recently emerging of sensors to be integrated in the concrete in order to measure some critical parameters, such as humidity and temperature and the internal pressure of the material. For example, by monitoring the pressure in various strategic points of the structure ... Read More

Standard measuring techniques for thermal conductivity cannot be readily applied to determine the load-dependent thermal conductivity of porous adsorbents, because the local ad- and desorption inside the specimen and the thickness of the specimen are not considered. Hence, in this work a ... Read More

COMSOL Multiphysics® can play a crucial role in jumpstarting undergraduate research programs in physics and engineering at colleges with limited financial support and small faculty size. The engineering physics program at Ramapo College of NJ has 48 majors and 4 full time faculty with ... Read More

A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar ... Read More

Over the last decade, ambient vibration energy harvesting by piezoelectric materials has been an area of extensive research. This technology enables to convert wasted mechanical energy available in our environment into useful electrical energy to power up autonomous wireless sensors ... Read More

Ultra-cold atom systems are excellent probes for various physical properties such as gravity, rotations or magnetic and electric fields. An integrated for solution for this technology is the atom chip, which uses magnetic fields in order to trap and manipulate ultra-cold atomic systems. ... Read More
