Although mammography is extremely important diagnostic technique, it suffers from some limitations such as false negative and positive results, using ionizing radiation and patient’s discomfort. Microwave imaging has been recently proposed as an additional medical imaging technique ... En savoir plus
We report here on the use of the COMSOL emw (electromagnetic waves) module in the design of a microwave launcher. This launcher is to be used in a microwave Doppler sensor that is incorporated into a chemical looping combustion system. The launcher is designed in two steps. First, we ... En savoir plus
A wireless passive pressure sensor and the measurement system were design and simulated using COMSOL 4.3. The sensor is based on MEMS capacitor attached to a planar inductor for wireless powering and readout. An external coil is used for the measuring system. The pressure to be measured ...

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... En savoir plus
For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra ... En savoir plus
Surface Plasmon Polaritions (SPPs), as electromagnetic waves localized at the surface of a metal, enjoy the unique properties to confine energy into sub-wavelength scale, which is beneficial for future photonic integration. However, the severe absorption caused by the metal influences ... En savoir plus
随着碳纤维增强复合材料(CFRP)在航空等领域的应用规模逐渐扩大，其低电导率带来的雷击风险得到广泛关注，CFRP雷击防护设计已成为研究热点，而雷电环境多理场仿真技术也在CFRP雷击防护设计中逐步发挥作用。目前，针对含雷击防护（如铺设防雷金属网）的CFRP平板结构雷击直接效应仿真研究已有一定成果，但是，对于铺设防雷金属网的CFRP-金属紧固件连接结构的雷击仿真鲜有研究。 本研究以铺设防雷金属网的CFRP-金属紧固件连接结构为研究对象，借助COMSOL Multiphysics重点分析了连接结构遭受雷击时的电-热多物理场效应。 ... En savoir plus
Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... En savoir plus
In the manufacturing of high voltage electrical equipment, an important step to guarantee a right dielectric design can be carried out through the prediction of a possible occurrence of the corona effect or, in the worst case, of dielectric breakdown, preferably in early stages. For this ... En savoir plus
