Modern electrical vehicle motors require a precise current control over the rotation of the rotor. These motors have high performance, but their control requirement impose a precise knowledge of the rotor angular position. Rotor position sensor (RPS) are traditionally designed using ...

Micro-lenses with potential applications in optics on the surface of the various heavy-metal oxide glasses were created and studied experimentally [1-2]. Laser direct writing using continuous-wave laser emitting at 447 nm was successfully performed [2]. The aim of this study is to ... En savoir plus

Raman spectroscopy is a commonly used tool in biodiagnostics and sensor technology. Surface-enhanced Raman scattering provides high signal enhancements especially at nanostructured metallic surfaces. In this paper the electromagnetic Raman enhancement from different metallic ... En savoir plus

A 3D model of a magnetic rotor both rotating and translationally moving at high-speed over a conductive guideway is modeled in steady-state using the convective A*-Φ formulation. The presence of the magnetic rotor (source field) is incorporated into the formulation via the boundary ... En savoir plus

The wide bandgap semiconductor silicon carbide (SiC) has drawn increasing attention in recent years as a promising material for high-power, high-frequency, and high-temperature operating devices. These outstanding properties of SiC make it a good candidate to replace silicon in many ... En savoir plus

Plasma, a complex fluid consisting of electrons, ions, neutrals, and excited species, exhibits both fluid-like behavior and electrical conductivity due to the presence of charge carriers. Consequently, computational modeling of plasma requires the integration of fluid and electrical ... En savoir plus

Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. Such enhanced local fields have many applications such as ... En savoir plus

        Surface plasmon polaritons (SPPs) are coherent oscillations of electrons at a metal-dielectric interface coupled to electromagnetic fields [1]. SPPs offer highly confined fields resulting in larger field amplitude and enhanced light-matter interactions. Control and manipulation ... En savoir plus

The renewable energy sector faces challenges in production processes due to geo-economic, and environmental issues. This had led to an increased interest in the use of solar energy as an alternative to fossil fuel based energy sources. In the solar energy field, significant research ... En savoir plus
