Perovskite solar cells (PSCs) are a promising photovoltaic technology but their performance remains limited by incomplete absorption of incident photons, primarily due to reflection at the transparent front electrode [1]. To address this issue, interface engineering with graphene-based ... En savoir plus

Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... En savoir plus

Induction heating (IH) [1] is a good candidate for decarbonization of chemical processes: energy savings, process intensification and production costs reduction [2-5]. Heat can be generated directly into the reactor at the surface in contact with the gas flux passing through a specific ... En savoir plus

Balises are an essential part of pointwise train control systems ensuring the operational safety. Combined with a corresponding onboard unit, it represents an inductive transponder system (Fig. 1). During a crossing, the balise is activated by the 27 MHz magnetic field of the vehicle ... En savoir plus

In the frame of an ESA project, CSEM in collaboration with other partners has developed an innovative Attitude Orbit Control System concept that relies on a Reaction Sphere. We propose to use one unique magnetic bearing Reaction Sphere whose spin axis and angular velocity can be ... En savoir plus

The article deals with the magnetically-supported high-power full-penetration laser beam welding of aluminum. A stationary simulation was conducted accounting for the effects of natural convection, Marangoni convection and solid-liquid phase transition as well as an electromagnetic ... En savoir plus

Electromagnetic forming (EMF) is a typical high speed forming process using the energy density of a pulsed magnetic field to form workpieces made of metals with high electrical conductivity like e.g. aluminium. This forming process can be very advantageous as compared to conventional ... En savoir plus

In this paper the propagation of a plane wave in a large lossy medium is presented. The investigated geometry consists in a wedgeshaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar ... En savoir plus
