This paper describes the thermal and structural combined simulation on COMSOL Multiphysics® of a Microwave (MW) Fin Taper (FT) Spatial Power Combiner (SPC) Power Amplifier (PA), based on rectangular Waveguide (WG). In the SPC based PA's, the captured power is feeded by microstrip ... Read More
Perfectly matched layers (PML) are an efficient alternative for emulating the Sommerfeld radiation condition in the numerical solution of wave radiation and scattering problems. The key ingredient of the PML formulation is the complex scaling function, which controls the anisotropic ... Read More
Surface Enhanced Raman Scattering (SERS) phenomenon is well known for its detection sensitivity, however, to better understand how it works a better insight needs to be developed on the physics behind the phenomenon. The physical aspects known to produce SERS effect are the use of ... Read More
Transient eddy current (TEC) technique is being developed for detection of flaws located at depth within multilayer aluminum structures. The present work involves finite element modeling using COMSOL Multiphysics software to simulate different types of probes by changing some of these ... Read More
Two transmitting planar microcoils (TX1, TX2) and one receiving microcoil (RX) are employed as shown in Fig.1 formed in induction-balance configuration. RX-Coil is positioned in such a way to achieve primary field suppression in RX-Coil’s region. Meaning, a magnetic cavity is created in ... Read More
Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous ... Read More
The most popular means of depression treatment are psychotherapy, antidepressant medication and recently adopted transcranial magnetic stimulation (TMS) of the human brain. To overcome their disadvantages we are investigating an application of low-field magnetic stimulation (LFMS) to ... Read More
Marco Cati graduated cum laude and encomium citation in electronic engineering in 2001 from the University of Florence, where in 2005 he also received a Ph. D. degree in electronic engineering. In 2005 he joined the Research & Development Department of Esaote where he is currently in ... Read More
This paper presents the design and simulation results of a MEMS-actuated deformable mirror (DM) consisting of a 20 × 20 Lorentz-force actuator array bonded to a flexible mirror. The DM is the critical component of an Adaptive Optics (AO) system targeted for ground-based telescope ... Read More
随着社会进步和发展，能源紧缺的问题日益突出。生物柴油因十六烷值高、无毒、可再生等突出优势正成为新能源开发热点。微波辅助生物柴油制备反应时间短、能耗小、环境污染少，所以设计高效的微波反应釜制备生物柴油势在必行。 针对微波反应器在生产生物柴油时加热不均匀的问题，本文设计了一种可以明显改善微波加热均匀性的夹层釜式微波反应器。然后，再引入能改善物料流体传热的搅拌桨装置。通过电磁场、温度场和流场控制强化液体物料传质传热，进而促进生物柴油的制备。本文所有的仿真工作均通过COMSOL软件进行，分别是用于计算反应器内电磁场分布的“电磁波，频域（emw）”接口 ... Read More
