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 electromagnetic force too. We compared the results of simulation using COMSOL and experiment under different ...

Surface plasmon polaritons (SPPs), which are confined along metal-dielectric interfaces, have attracted great interest in the area of ultracompact photonic circuits due to their strong field confinement and enhancement. COMSOL Multiphysics is an efficient and powerful software package to simulate the characteristics of SPPs. In recent years, we did some works on SPPs in experiments as well as ...

In this section, we design an invisible cloak using the composite medium of silver nanowires with elliptical cross-sections embedded in a polymethyl methacrylate host. Under the guidance of an analytical effective medium approach, we use the parameter retrieval method to design a well-performed invisible cloak, based on an empirical revised version of the reduced cloak. The cloak is numerically ...

COMSOL Multiphysics is a very helpful simulation software in our researches on both PEMFC and nanometer-sized electrodes. In the first part of our presentation, the influence of humidity and temperature to the performance of PEMFC are studied by simulating the MEA (membrane electrode assembly) in PEMFC. In the second part, models of different nanometer-sized electrodes, including spherical ...
