At the Fontys University of Applied Physics (The Netherlands) a plasma etcher has been acquired for educational purposes. The machine operates at low power up to 30 Watt and is driven with a magnetic coil at 13.56 MHz. The use of COMSOL Multiphysics software will be discussed to simulate the temperature and mass fractions of the activated and ionized atoms in the gas. The simulations will be ...

An ion trap resonator, used for mass spectrometry, is investigated. Simulations are used to define the stabilization criterion of ion trajectories by optimization of the electrode configurations. The ion interactions are investigated and shown to help in reduction of ion-diffusion. Space charge effects simulate the induced voltages on pickup electrodes.

Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace components. With the aid of COMSOL Multiphysics software, the time-dependent creep deformation behavior of a heater ...

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. This work presents a robust approach to the design of EM Shielding based on Graphene (Gph) layers. It is a two ...

It is well-known that metal nanoparticles (NPs) excited at the plasmon frequency not only exhibit peculiar optical properties (e.g., a peak in the extinction spectrum, an enhanced electromagnetic near-filed) but also heat up . This phenomenon is highly investigated for medical applications, but it can be exploited also for the realization of optical devices. In our study we use COMSOL ...

Parallelization of microfluidic droplet generators is one of the major challenges that droplet microfluidics has to overcome to contribute significantly towards the sustainable manufacturing of advanced materials such as nanoparticles, quantum dots, active pharmaceuticals, etc. A massive parallelization system needs to maintain consistency and uniformity across all droplet makers. To achieve ...

This paper study the mechanical response of a granular solid subject to an impulse force. The proposed model simulate the behavior of an airport pavement structure. The analysis is performed on a representative volume element (RVE) under thermo-mechanical actions, as those produced by landing gear impact of an airbus A320 and variable high surface temperatures loads. The model, implemented in ...

The integration of high level of stress in field effect transistors is performed through incorporation of intrinsically strained SiGe layers. With the help of COMSOL simulations, we performed two studies addressing the level of stress in the area of interest. In the first case, we analyzed the geometric effects of the SiGe film stress relaxation on the edges. In a second time, we studied the ...
