Modeling of a Switchable Permanent Magnet Magnetic Flux Actuator
A simple magnetic circuit consisting of ferromagnetic core material, air gap, permanent magnets and current coils can be used to form magnetic actuators, motors etc. devices. In this work the current coils are not used to generate working magnetic field, but just to switch magnetic flux ... 詳細を見る
Advanced Application of an Automated Generative Tool for MEMS Based on COMSOL Multiphysics
This work presents a different use of COMSOL as an integrated component of a computational tool framework used to automate designs creation. CNS-Burst is a computational synthesis method that has been implemented with the aim of automatically generating solutions to an assigned design ... 詳細を見る
Efficient Simulation of 3D Electro-optical Waveguides Using the Effective Refractive Index Method
3D FEM simulation of millimeter-scale, complex electro-optically induced waveguide based devices demands the use of grids with more than several million nodes. Hence the simulation could take substantial time and require large amounts of available memory. This paper presents a ... 詳細を見る
Modeling of Through-the-Snow Electric Field Propagation for Rescue Systems
Propagation models for avalanche rescue systems are studied here. The paper focuses on the through-the-snow electric field propagation at ISM frequencies, comparing several models (air model, snow model, three-layered model) and using different solving method (geometrical optics, ... 詳細を見る
Microwave Plasma Simulation Applied to a Double ICP Jet Reactor
ICP reactors are usually meter sized and driven at RF frequencies, for example at 13.56 MHz. We developed a miniature resonator allowing an inductive type of coupling of microwaves at 2.45 GHz to a plasma jet, flowing in ceramic tubes. Previous experiments and simulations show an ... 詳細を見る
Simulation and Verification of a Capacitive Proximity Sensor
State of the art proximity sensors are most often based on optical or tactile methods. Although these sensor systems are widely used (e.g. clamping protection) the reveal several drawbacks. Most optical sensors need a line of side whereas tactile sensors cannot be used to determine a ... 詳細を見る
Modal Characterization of the Plasmonic Slot Waveguide Using COMSOL Multiphysics
We investigate and compare the characteristics of the fundamental guided mode sustained by a subwavelength plasmonic slot waveguide for three types of metals: gold, silver and aluminium. This is done in terms of mode effective index, propagation length, confinement and, as the mode under ... 詳細を見る
Numerical 3D-FEM-simulation Made By COMSOL Multiphysics of a Microwave Assisted Cleaning System for a Diesel Sooty Particle Filter and its Experimental Validation
By means of a numerical 3D-FEM-simulation, some alternatives for the arrangement of the waveguide supplying the microwave energy to a cylindrical ceramic filter are investigated. The different alternatives are compared concerning a homogenous distribution of the electromagnetic field and ... 詳細を見る
Current Distribution and Magnetic Fields in Complex Structures Using Comsol Multiphysics
The present paper presents numerical calculations of the magnetic fields and the current distribution within a wind turbine nacelle. The results are used by control system engineers designing panels and cables, who must ensure that the immunity of the equipment complies with the ... 詳細を見る
Super-lattice Effects in Ordered Core-shell Nanorod Arrays Detected by Raman Spectroscopy
We studied the optical phonon excitations (LO) of ordered arrays of dot/ rod core-shell CdSe/ CdS nanorods by Raman spectroscopy. Upon deposition on planar substrates the nanorods formed super-lattice structures via side-by side assembly into tracks over some microns of length. COMSOL ... 詳細を見る
