Introduction: In inductively coupled plasma (ICP) systems the inductive antenna is coupled to the excited plasma inside the low pressure gas reactor. A multi-ICP system can be used for increased area processing and provide additional variables for controlling the plasma. However, ... En savoir plus
Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud ... En savoir plus
Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection ... En savoir plus
Fixed nitrogen is used in many forms ranging from nitric acid to hydrogen cyanide and is used as such for industrial applications. The reactions to produce these products are highly endothermic and favored by high-temperature processing. The most basic route of chemically fixing nitrogen ... En savoir plus
Within this study a model of a single discharge of micro scale EDM was developed in accordance with Schulze et al [1]. The specific computation of the growth of the plasma channel has been derived from this literature. Applying COMSOL Multiphysics® a pseudo 3-D geometry was created based ... En savoir plus
Large-area, light-weight electromagnetic protection (EP) structures are needed to protect sensitive microwave sensors and communications systems from high-power microwave (HPM) and electromagnetic pulse (EMP) threats. This paper presents the use of COMSOL Multiphysics® for ... En savoir plus
The Helicon-Injected Inertial Plasma Electrostatic Rocket (HIIPER) is a two-stage electric propulsion system comprising of a helicon plasma source and an inertial electrostatic confinement (IEC) device for plasma production and acceleration, respectively. Several diagnostics such as a ... En savoir plus
Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... En savoir plus
A discrete model for the prediction of relative ion bombardment flux and target erosion in planar sputtering magnetrons is implemented in COMSOL Multiphysics®. Planar magnetrons are used within physical vapor deposition (PVD) processes to form thin film depositions on various types of ... En savoir plus
