The flow of electrically conducting fluids such as liquid metals is significantly affected by applied electric and magnetic fields. The effect has important industrial applications in metallurgy, nuclear technology and other fields. This paper described results of a series of studies ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
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 ... 詳細を見る
Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world ... 詳細を見る
在微波加热的多物理场仿真中，如果被加热物体的几何区域太小或者太薄，会造成整个模型网格剖分困难、网格数量多且计算消耗内存大等问题。本文针对微波加热时薄壁容器的网格剖分困难，网格数量大，且占用计算机内存资源多的问题，提出了一种基于变换光学算法的微波薄壁加热模型计算优化方法。利用变换光学算法将薄壁区域空间扩大，通过改变薄壁区域内的介质参数来与原模型进行空间映射，从而避免网格剖分过程中的薄壁问题出现，这样可以在同样的网格剖分设置下减少整个模型的网格数量，节省计算时间，减少计算机内存资源的占用。通过相应的公式推导，在二维模型中实现了薄壁变换光学算法的计算 ... 詳細を見る
Pulsed eddy current (PEC) is being developed to detect stress corrosion cracks between fasteners on the inner wing spars of the F/A-18 Hornet aircraft. The spars are located below a thick carbon/epoxy wing skin, and so cannot be detected by conventional eddy current techniques without ... 詳細を見る
