Optical devices are generally simulated using ideal structures. These ideal geometries are critical in finding major features of the optical response. Unfortunately, fabrication of such devices rarely results in structures that are ideal.[1] In particular, surface roughness is rarely ... En savoir plus

Transition metal dichalcogenides (TMDCs) have attracted the interest of researchers because of their physical properties, such as tunabilitiy, non-zero bandgap, gas sensing and superconductivity. One of the most studied TMDC is monolayer MoS2, for this reason we present how COMSOL can be ... En savoir plus

Plasmonics is a new branch of the fascinating field of photonics and develops concepts to quench light beyond the diffraction limit and enhance electromagnetic fields. These enhancements occur in metals as localized surface plasmon polaritons (LSP) a coupling of the surface density ... En savoir plus

In this study, for the first time, we have carried out three dimensional transient magnetostructural analysis of a Magnetic Pulse welding (MPW) system which welds two tubular work pieces of dissimilar conducting materials. For this purpose a finite element model (FEM) is developed using ... En savoir plus

Lyophilization is a food preservation process that allows to inhibit the growth of bacteria and other contaminants by removing water content in the processed food. Conventional vacuum dryers provide heat by thermal conduction to assist the phase change transformation, but if the product ... En savoir plus

As part of our primary research focus, we explore the phenomenon of non-radiative resonance energy transfer (RET) between a pair of dipoles positioned within a hyperbolic metamaterial (HMM). Our investigation reveals that the presence of an HMM can fundamentally alter these non-radiative ... En savoir plus

Attosecond light pulses have revolutionized our view of fundamental atomic, molecular and solid state processes in the attosecond - femtosecond time domain [1]. The availability of such pulses is based on high-order harmonic generation (HHG) in noble gas samples by a femtosecond laser ... En savoir plus

Metamaterials are composites of subwavelength structures that can be engineered to affect the propagation of a wave in specific ways as it travels through the material. While metamaterials can be used with any type of wave, they are most commonly found in electromagnetic waves. However, ... En savoir plus

This paper deals with the numerical simulation of Annular Linear Induction Pump (ALIP) using Finite Element Method based software COMSOL Multiphysics® . ALIP is used for pumping of liquid sodium in various experimental facilities and in auxiliary circuits of fast reactors. Usually, the ... En savoir plus
