High power Lower-Hybrid RF waves injected at in a Tokamak plasma can strongly modify the edge plasma. This is caused by ponderomotive forces pushing charged particles in an inhomogeneous oscillating electromagnetic field towards weaker field areas. On the Alcator C-Mod Tokamak, edge ... 詳細を見る
Microwave imaging has been recently proposed as a potentially useful screening technique for breast cancer. This method detects abnormalities in the tissue based on permittivity difference between breast normal and malignant tissue. In this method breast is illuminated by high frequency ... 詳細を見る
The classical optimization method has been applied to many design problems for electromagnetic systems. One of its major difficulties is related to meshing problems arising from shape modifications. In order to circumvent these kinds of technical difficulties with moving mesh problems, ... 詳細を見る
This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... 詳細を見る
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 ... 詳細を見る
With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... 詳細を見る
The actuation system of the deformable mirror is one of the crucial components of an Adaptive Optics unit. One possible implementation comprehends a linear force motor and a capacitive sensor providing the feedback measure signal. Choosing a magnetic circuit that makes optimum use of the ... 詳細を見る
