Photonic crystals (PhCs) are the periodic arrangement of dielectric structures in one, two and three dimensions offer unprecedented control of light including inhibition of spontaneous emission, negative refraction, self-collimation and confinement. Due to the advent of three-dimensional ... 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

An simple analytical model for the calculation of the resonance frequency of coils typical consists of a network of inductance, capacitance and resistance. Calculating these three parameters based on spatial geometry is not easy in most cases. The finite element method as used in COMSOL ... 詳細を見る

Multiphysics acoustics is increasingly used to design products to meet sound, ultrasound and infrasound and other structural, thermal, electromagnetic requirements. In this paper, Multiphysics Acoustical applications such as digital stethoscope, glazing products and acoustical ... 詳細を見る

The advent of wireless power transfer (WPT) technology has offered a gradually evolving research field with a multitude of triggering applications, like electric vehicles, bio-medical implants and wireless charging media for consumer electronics. However, since the initial establishment ... 詳細を見る

We consider the problem of calculating forces on high current solid conductors, as is present e.g. in substations[1]. This is of importance for the design of the station, in particular for the conductor geometry and mechanical support. The full calculation includes a treatment of the ... 詳細を見る

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... 詳細を見る

To overcome the uneven heating during the process of microwave heating of food inside microwave oven, a geometrical model based on domestic microwave oven with a cylindrical container composed of multi-materials(with two different kinds of materials, one half is glass and the other half ... 詳細を見る

PECM is a necessary extension to traditional ECM for some high-performance materials. Electrolyte flow in the inter-electrode gap (IEG) can be assisted using a magnetic field to allow higher currents, but this creates a magnetohydrodynamic flow. This paper presents a study of flow ... 詳細を見る

Trefoil cable formation is used where three phases are carried by three single core power cables, rather than a single three phase multicore cable. The advantage of installing three single cores in such a configuration is that it minimises the induction of eddy currents, therefore ... 詳細を見る
