We present examples of the use of COMSOL Multiphysics for the solution of electrical conduction in varistors coupled to the solution of long-term heat-transport through conduction and convection. We fit measured power-loss and impedance data with analytic functions in order to simulate ... 詳細を見る

This paper describes a numerical solution method for the simulation of a cold crucible induction melting (CCIM) process involving the coupling of electromagnetic, temperature and turbulent velocity fields. During the CCIM process, the metal charge is contained on a water cooled ... 詳細を見る

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

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

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

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

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

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

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

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
