A proton linac drives particles using the electric field of a high power RF standing wave in a resonant cavity. The design of these cavities involve several aspects of multiphysics simulation, that have been accomplished using COMSOL. The first step consist on the geometric optimization ... 詳細を見る

The use of microwaves for heating purposes of dielectric materials is encountered in many industrial applications (food processing, chemistry, material engineering and medical applications). In most of these thermal applications, the prediction of the temperature evolution within the ... 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

A new regulation for the safety assessment of dams has just been developed in Italy and its approval process is still in progress. As a matter of fact the behaviour of dams under seismic loading conditions is deemed of actual interest due to the recent seismic events occurred. In ... 詳細を見る

In this article, the aim is to study different types and forms of electromyography (EMG) electrodes, for bipolar configuration, and the electric interface with muscle phantom. COMSOL Multiphysics allows modeling shapes and contact surfaces. Surface and needle electrodes will be modeled. ... 詳細を見る

While low frequency light is poorly transmitted through an aperture in a conductive thin film, in the phenomenon known as extraordinary optical transmission (EOT), a narrow band of selected frequencies are transmitted when incident on an array of subwavelength periodic apertures where ... 詳細を見る

When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... 詳細を見る

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

Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis ... 詳細を見る

COMSOL analysis of the acoustic modes of two different Combustion Wind Tunnel Facility’s test sections was conducted in this project. The test sections are rectangular ducts, therefore the mathematical expressions to predict the longitudinal and transverse modes inside a tube were used ... 詳細を見る
