In this paper it is shown how the equivalent circuit parameters of a MEMS resonator can be simply obtained from an eigenfrequency simulation. Additionally, it is demonstrated that the Q-factor as a result of support losses in a MEMS resonator can be determined using a matched boundary ... 詳細を見る
An inverse finite element method for noise source identification in an aircraft cabin is presented. If all sound sources are located on the boundary of the cabin, the equation system resulting from a matching FE model can be re-sorted in such a way that computation of the unknown ... 詳細を見る
Some types of mechanical devices, such as molds, but not only, include a large number of micro-mechanisms, valves, channels, vents, or other devices subject to deterioration or malfunctioning, frequently caused by unwelcome phenomena such as incrustations, fillings, or reciprocal bonding ... 詳細を見る
In the past few years, metamaterial perfect absorbers (MPA) have been extensively studied due to their incredible ability to manipulate electromagnetic waves and provide a broadband, polarization-independent, and wide-angle response for a host of applications. The need for high ... 詳細を見る
During last twenty years capacitive micromachined ultrasonic transducers (CMUT) have been developed extremely fast [1-2]. CMUT is an attractive alternative to traditional piezoelectric transducer, which converts electrical signal to mechanical vibration and vice versa. The main ... 詳細を見る
The performance of simplified cylindrical cloaks with various material parameters was investigated. The performance metric was the overall scattering width of the cloak with various objects in the hidden region. COMSOL was used to simulate three cloaks with different material parameters ... 詳細を見る
An simple analytical model for the calculation of the resonance frequency of coils typical consists of a network of inductance, capacitance and resistance. Calculating these three parameters based on spatial geometry is not easy in most cases. The finite element method as used in COMSOL ... 詳細を見る
In this study, we propose an absorbing boundary domain (or condition), which is really simple but still efficient for the 2.5D finite element (FE) analysis. The main application is to simulate the electromagnetic (EM) waves related to the marine controlled source electromagnetic (CSEM) ... 詳細を見る
Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing ... 詳細を見る
电阻抗成像（EIT）技术由于分辨率较低受到专家学者的诟病，而EIT与超声技术两者的结合以及 EIT 与磁共振技术两者的结合可以提高成像的分辨率，但仍分别存在电极射频屏蔽效应以及分辨率难以进一步提高等问题。本文将磁共振成像技术和磁声电技术优势互补，采用低频振动进行激励，提出了一种新的动电成像方法，并采用 COMSOL 软件建立了二维仿真模型，使用 PDE 模式对动电阻抗成像的正问题进行了仿真研究，利用 COMSOL 的仿真结果结合Matlab软件进行了反演，实验结果可以反映出仿真模型内部的电导率分布，能够解决上述电阻抗成像结合技术存在的问题。 詳細を見る
