In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not ... Per saperne di più
For automotive applications, simulation methods are used to get the best audio acoustic performance. Because a loudspeaker is a non linear device, the sound pressure in the vehicle includes harmonics which are mainly created by the force factor, suspension stiffness and voice coil ...

The prediction of the exact location and intensity of the electric field induced in the human brain during Transcranial magnetic stimulation is a nontrivial computational task. Numerical simulations of the procedure can be used to acquire first approximations in a safe and controlled ... Per saperne di più
Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection ... Per saperne di più
In this paper, we consider the finite element modeling of multilayer transmission lines for high-speed digital interconnects. Using COMSOL we mainly focused on the modeling of the transmission structures with both cases of symmetric and asymmetric geometries. We specifically designed ... Per saperne di più
The design of a magnetic resonance imaging (MRI) RF coil using finite element method-based analysis is an essential part of a multi-year research project at the National Institute of Standards and Technology, Gaithersburg, Maryland, where the goal of the project is to develop a “phantom” ...

In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the ... Per saperne di più
Bioreactor landfill is based on a homogeneous distribution of the moisture content to increase waste biodegradation. Most of studies have shown that Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D). ERT is influenced by many ... Per saperne di più
Modern electronic assemblies and printed circuit boards (PCB) with their sensitive structures and elements have to be protected against environmental influences by conformal coating or casting compounds. In this case the main challenge is the simultaneous curing of the polymers and the ... Per saperne di più
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。 Per saperne di più
