The use of a reaction sphere as an actuator used by satellite Attitude Control System was proposed over twenty years ago. In principle this concept assumes the use of a single reaction sphere which can be accelerated in any direction instead of a set of reaction wheels. The solution ... En savoir plus
Surface plasmon resonance (SPR) sensors proved themselves as a promising device for many kinds of applications such as optical biosensing, binding constant determinationor nanofilm thickness measurements. Here we simulate using COMSOL Multiphysics® the light-polaritons coupling for the ... En savoir plus
We theoretically studied the microwave coplanar line of different geometry based on MgO substrate with a thin (30 nm) ferroelectric layer under the external electric field using the environment of 3D modeling in COMSOL Multiphysics®, RF Module, Frequency Domain. Frequency dependence of ... En savoir plus
Metallic nanoparticles (NPs) are nowadays used in various areas of biology, chemistry or physics. Focused laser beams, optical tweezers, may be used to manipulate such NPs. However, experimental studies showed that there is a discrepancy between their predicted and observed behavior. ... En savoir plus
For the SAFARI Imaging Spectrometer, part of the SPICA satellite payload, a Calibration Source is under development. Challenges in the design include the low cooling power (few mW) available at cryogenic temperatures. COMSOL Multiphysics® simulations were used extensively in the design ... En savoir plus
We present a simplified 3D model that simulates the operation of a linear microscale integrated ion trap. It employs a set of metalized electrodes, which are formed on top of an insulator layer on silicon substrate. The confinement in all three dimensions is provided by the application ... En savoir plus
A neutrino oscillation experiment aims to the observation of the transformation of a neutrino of a given flavour into a neutrino of a different flavour. A beam of neutrinos is produced through the decay of charged pions which in turn are produced in the collision of high energy ... En savoir plus
MRI offers many advantages over other modalities and its lack of ionizing radiation is important for children, but can be limited by the radio-frequency (RF) coils available. This work calculates Specific Absorption Rate (SAR) and homogeneity of the RF transmit field (B1+) when imaging ... En savoir plus
Nano-structures consisting of layered metal-dielectric stacks (MDSs) can be designed to have evanescent transmission and reflection coefficients that oscillate as a function of transverse wavevector and frequency. However, these structures always suffer from the material losses and ... En savoir plus
The prediction of the exact location and intensity of the electric field induced in the human brain during Transcranial magnetic stimulation is a nontrivial computational task. Numerical simulations of the procedure can be used to acquire first approximations in a safe and controlled ... En savoir plus
