This paper presents a new design methodology of quasi-conformal transformation optics (QCTO) based modified Luneburg lens antennas using a broadband anti-reflective (AR) layer. The design used QCTO technique to modify portion of the lens’s spherical geometry into a flat surface for ... En savoir plus

For the development of a Permanent Magnetic Synchronous Machine (PMSM), optimization of design variables, e.g. the size of an air gap, is performed. When applied to optical instruments in space environment, the motor has to be designed for ultra high vacuum (UHV) and cryogenic ... En savoir plus

This paper presents the quasi-TEM two-dimensional (2D) approach for the analysis of multiconductor transmission lines interconnect in single and two-layered dielectric region using the finite element method (FEM). FEM is especially suitable and effective for the computation of ... En savoir plus

One of the primary reasons for large power fluctuations in smelting furnaces is loss of contact between the electrode and ore. Therefore one of the important aspects of controlling power fluctuations is a predictive algorithm for the positioning of the electrode. We propose a model ... En savoir plus

Plasmonic-based optical trapping is in its infancy and growing rapidly. Research in this area will significantly advance fundamental understanding in fields such as nanophotonics and biophotonics. Novel plasmonic trapping structures and systems can be designed and optimized using the ... En savoir plus

In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... En savoir plus

The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. The LHC machine consists on a 27 km circumference tunnel that accelerates and collides proton beams and heavy ions. The High Luminosity LHC (HL-LHC) is a project aiming to upgrade the LHC ...
