A piezoelectric transformer allows purely mechanical transfer and scaling of electrical energy via simultaneous utilization of both the direct and converse piezoelectric effects. This mechanical energy transfer enables a wide range of functional differences from typical magnetic-based ... 詳細を見る
The photoacoustic (PA) effect consisting of the generation of an acoustic signal based on the absorption of light has already demonstrated its potential for various spectroscopic applications for both gaseous and solid samples. The signal produced during photoacoustic spectroscopy (PAS) ... 詳細を見る
精确监测电缆载流量对海南联网系统500 kV海底电缆的规划和运行具有重要意义。目前进行载流量计算的方法主要分为三类:解析法、数值解法和试验测试法。数值解法是进行海底电缆温度场分析时最常用的方法,其中有限元法能很好的模拟各敷设情况下电缆的实际运行情况,省去了实地测试成本,又保证了计算精度。本文利用COMSOL仿真软件研究了一种基于分布式光纤传感技术的海底电缆载流量多物理场仿真方法。 根据海南500kV海底电缆敷设的实际情况，建立四种不同的仿真模型，分别为空气裸露段、登陆段、潮间带和海床。根据不同模型中海底电缆、光缆的物理参数和外部环境物质的材料设置边界条件 ... 詳細を見る
Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor / magnetic material configuration, using FEA software to calculate the resulting field, modifying the configuration, and iterating to produce the desired field. Our method involved solving the ... 詳細を見る
The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... 詳細を見る
Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... 詳細を見る
Vacuum phototriodes (VPT) have been used as photodetectors for many years in particle physics experiments. For example, they were used in the OPAL experiment at LEP and are currently used in the endcap Electromagnetic Calorimeter of the CMS experiment, at CERN’s Large Hadron Collider. ... 詳細を見る
The Finite Element Method (FEM) has become an established numerical tool used for different academic and industrial purposes. It allows the prediction of weld pool geometry, thermal cycle, final distortion and residual stress field during and after fusion welding. The capability of the ... 詳細を見る
Terahertz (THz) technology has been receiving expanding interest in the recent years due to its rich scientific and potential application. For instance, a variety of semiconductor phonons resonate in the THz range; macro-biomolecules have unique fingerprint lines in the THz range; less ... 詳細を見る
In this work, an analysis is presented for a 3-dimensional RF MEMS coil using the COMSOL AC/DC module in conjunction with the CAD import module. The realization of being able to produce such 3-dimensional RF coils allows for less surface area to be needed for similar inductor performance ... 詳細を見る
