It was suggested long ago that a theoretical model of a near-cathode region in a DC glow discharge admits multiple steady-state solutions describing different modes of currrent transfer. Even the most simple self-consistent models should admit such multiple solutions. In the present ... Read More
The well known Pierce design of electron and ion diodes is the base of particle source extraction systems [1,2]. It was heavily studied up to 1960 with analog computing and it now offers us a known case against which to compare the precision of fluid and particle tracing codes. The ideal ... Read More
A horizontal array of Si microlines (line width ~1 µm) was formed on a Silicon-on-Insulator (SOI) wafer [1] and was used as a photodetector to study the photoresponse in the wavelength range 400 nm to 1100 nm. The fabrication of partial suspended Si microstructure array was made using a ... Read More
由于能源的消耗，太阳能电池越来越受到人们的关注。然而，作为商业中主要应用的晶硅太阳能电池存在表面入射光反射以及无法吸近红外光的性质限制了晶硅太阳能电池效率的进一步提高。因此，我们设计了一种内嵌二维光子晶体纳米圆锥的频率上转换超薄晶体硅太阳能电池，其中铒镱共掺氟化钇钠(NaYF4:Er3+/Yb3+)上转换层夹在Ag背反射层和活性层中间，利用COMSOL Multiphysics ®中波动光学模块系统的研究了具有不同结构和电介质填充材料纳米圆锥阵列对频率上转换晶硅太阳能电池陷光增效的影响。利用周期性边界条件及有限元的思想构建了电池计算单元，在300-1150 nm ... Read More
Divertor is act as an exhaust for the nuclear fusion reactor. Main function of a divertor is to remove the heat flux from the plasma. Plasma facing components of the divertor are made up of Carbon (Graphite/CFC) and tungsten like materials[1]. Hence these materials are exposed to the ... Read More
Current transfer from high-pressure arc plasmas to thermionic cathodes may occur in a diffuse mode, when the current is distributed over the front surface of the cathode, or in a spot mode, when most of the current is localized in one or more small areas. Spectra of perturbations of 3D ... Read More
2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ...

Recent developments (1) in thermal metamaterials that enhance the response of thermoelectric generators (TEG) have revived the interest in TEG research. The COMSOL Multiphysics® software offers the unique opportunity to model TEGs with various cooling systems (air, water, etc) and ... Read More
Pseudospark (PS) discharge is a low pressure hollow cathode discharge for generation of high intensity and high current density electron beams [1-3]. As the frequency of the microwave devices increases, the dimensions of the beam-wave interaction region gets reduced. In THz frequencies, ... Read More
The design and analysis of a multidimensional system involving multiphysics considerations requires solving of complex equations. A high power continuous wave RF component is one such system. The poster reports the design, multiphysics analysis, low and high power experimental results of ... Read More
