Technical Papers and Presentations

In the recent years, Rai Research Centre (CRITS) has been involved in investigating solutions to guarantee a satisfactory coverage of Digital Audio Broadcasting (DAB) service, in the 200 MHz frequency band, for challenging scenarios like tunnels. Preliminary field tests receiving the RF ... Read More

The simplicity, reliability and low costs of electro-mechanical breakers have made them the workhorse for the interruption of low voltage short-circuit currents. In the presence of a short circuit, the contacts of the breaker heat up, and a bridge of molten metal forms between the pair ... Read More

Campi Flegrei Caldera is an active volcano located westward of Naples, Italy. Despite its volcanic activity spanning over 39,000 years, the area is densely populated and poses a significant threat to the inhabitants due to ongoing seismicity, ground uplift, and hydrothermal activity ... Read More

Friction Stir Welding (FSW) is a solid-state joining technique that has become increasingly popular and efficient for welding both similar and dissimilar metallic materials. Despite its success in joining dissimilar materials, further development is necessary to meet industry ... Read More

The paper describes how the fluxgate current sensor works and how it is built in the COMSOL Multiphysics® software. Four COMSOL® modules were used: -AC/DC Module: the magnetic field physic is used in order to apply the Ampere-Maxwell’s law to the different sensor components and to the ... Read More

In this paper, the topic of frequency-controlled manipulation of sinking particles in a stationary liquid column based on AC dielectrophoresis is studied in depth. Particles sink downwards within a liquid column due to the gravitational force. In doing so, they are subjected to Stokes ... Read More

Metasurface (MTS) antennas are based on the use of special types of scattering surfaces patterned at a sub-wavelength scale with electrically small metallic dielectric inclusions, usually called unit cells [O. Quevedo-Teruel et al., Journal of Optics, vol. 21, 2019]. The radiation ... Read More

The new FE Toolbox from Lauterbach Verfahrenstechnik GmbH combines precision and user-friendliness in one application. Our tool is tailor-made to reliably achieve a fast and accurate design of various components in pressure vessel design and plant design. With COMSOL Multiphysics we have ... Read More

We present a problem-adapted finite element model, which enables the design of a novel type of a highly miniaturized, electrostatic MEMS membrane pump, as well as the investigation and the optimization of its operation. The electro-mechanical actuation scheme constitutes a strongly ... Read More

Induction heating (IH) [1] is an electrically driven process useful for decarbonization of the industry. It can be used for electrification of chemical processes to replace traditional heating with gas burner and avoid CO2 emission. This kind of process can be used to heat efficiently ... Read More
