Electrokinetic (EK) techniques have been broadly implemented in a variety of fields, including microfluidics and lab-on-a-chip, and are seeing increased interest to miniaturize and optimize fluid pumping and mixing systems. While EK techniques such as electro-osmosis and ... En savoir plus
Seawater can be converted into fresh water using solar energy. This is as an easy, suitable and green solution method to obtain heat for desalination. It is possible to concentrate the sunlight heat flux onto a small focal area by using a Fresnel lens. When the focal area is correctly ... En savoir plus
The multiphysics analysis of a 130 GHz klystron is described in this paper. Critical quantities are exposed to multiple physics effects acting on narrow dimensions modified by power dissipations. The proposed device uses an integrated injection/bunching section described in last COMSOL ... En savoir plus
The aim of this research is to study the electrostatic properties of heterogeneous media that have fractal geometries. Currently, composite dielectrics are assumed to have regular geometric structures (integer-based dimensions) and an isotopic, homogeneous dielectric permittivity; but, ... En savoir plus
A well-collimated intensity profile at long distance has long been a desired laser property crucial for many potential applications. Extending a non-diverging range for ordinary laser beyond kilometers scale would permit superior performance for optical technologies, including LIDAR, or ... En savoir plus
Linear motor has a lot of applications, such as magnetic levitation train, electromagnetic weapons. It is a very important research significance. We established a three-dimensional model of linear motor to calculate the magnetic field lines and flux density distribution, and got the ... En savoir plus
