Several commercial CFD companies have recently extended their codes to magnetohydrodynamic (MHD) flows. However, there are many computational challenges associated with MHD flows under the harsh fusion environmental conditions that require such codes to be carefully examined in a special ... Read More
The modelling of a ferrite material is conventionally carried out using the Polder permeability tensor which assumes that the ferrite is saturated by a uniform magnetic field. This assumption is often inaccurate due to the constraints imposed by boundary conditions which renders the ... Read More
Waveguide Structures are often used for transmission of high CW power. The inherent conductor losses in the waveguide material lead to an increase in its temperature. If appropriate thermal management is not undertaken, this high temperature may lower the breakdown threshold of the ... Read More
Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... Read More
The high power of X-ray beam delivered by synchrotrons and free electron lasers, up to 240 W/mm2, requires heat load management solutions to obtain the best performance from the optical elements which will shape the beam for its use in the experimental stations [1]. One solution is the ... Read More
Surface Plasmons (SP) or Surface Plasmon Polaritons (SPP) are electromagnetic excitations that propagate at the interface between a dielectric and a conductor, and are evanescently confined in the perpendicular direction to the propagation. They arise via coupling of the electromagnetic ... Read More
Vacuum window is required in the millimeter wave transmission line in ITER*. It is to be designed to minimize the microwave reflection while keeping a robust and safe approach to meet the requirements. We have studied transmission characteristics of various dielectric materials over D ... Read More

摘要：在太空高能带电粒子作用下，航天器上存在绝缘介质深层充电的危险。介质内沉积电荷导致局部出现强电场（达到107V/m），有可能造成介质击穿放电。一方面，充电过程与介质电导率密切相关，而电导率受温度影响显著，另一方面，介质中的通电导体发热会影响介质的局部温度，于是有必要综合考虑介质中电场与热场的耦合变化过程。对此，我们建立了考虑电场与热场耦合变化的介质深层充电模型，并采用 COMSOL Multiphysics® 软件，实现了数值求解。结果表明，在一定的空间辐射环境下，考虑热场是十分重要的，热导率会对充电结果产生不可忽视的影响 ... Read More
