In this paper we want to figure out the development of a capacitive acceleration-sensor system with the FEM-Method. The sensor-system is in the position to detect accelerations in the range of ±20 g. Furthermore the sensor-element contains a printed RF-inductance, which is used for contactless data transfer. On the one hand the simulation of the L-C-oscillating circuit using the RF Module of ...

FMR spectra of the periodic microstructures (one-dimensional magnonic crystals, 1D MCs) were obtained using COMSOL with use partial differential equation interface. Results of these calculations were successfully compared with an experimental data for Damon-Eshbach (DE) and Backward-Volume (BV) geometries. The presented tool allows to analyze periodic structures with various geometries and ...

Performance degradation of a superconducting RF cavity after quenching in an external magnetic field was calculated using COMSOL. This degradation is due to the increased resistance of a superconducting surface with trapped magnetic flux. The amount of the trapped flux depends on the size of the normally-conducting opening that develops in the superconducting wall of a cavity during quenching. ...

Introduction: Domestic microwave ovens are widely used to heat food products, because of rapid and convenient heating. Nonuniform heating is the biggest issue in microwave heating process, which also causes food quality and safety issues. Microwave heating models are promising tools to assist in developing food products that deliver uniform heating. Due to intensive heating, moisture evaporation ...

Microwave heating is an important process for many commercial, industrial and household applications. In microwave heating applications, the energy is introduced directly into the volume of the material. As a consequence the quality of the process is highly dependent on the uniformity of the electromagnetic field distribution. Thus, developing a uniform electromagnetic field inside the ...

Previous studies proposed using bipolar radiofrequency ablation across two catheters placed on opposing surfaces of the ventricular wall to create transmural lesions. 2D and 3D models were built and solved with COMSOL Multiphysics software. With these models, it was possible to study the temperature distribution and lesion geometry (Figure), to compare the potential of two ways of applying ...

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission ...

The optical scattering and absorption of gold nanorods (GNRs) depends on its size, shape, and surroundings. This dependence is due to both intrinsic and extrinsic effects. A good understanding of this dependence is needed for applications of GNRs in photo-thermal therapy, optical and opto-acoustic imaging, biosensing, and other photonic areas. Extrinsic effects are caused by the production of ...

In order to perform rust surface treatment for stainless wires, we proposed an electrolyzing equipment to do so. It has the following advantages: safer, cheaper and less environmental pollution. To study the performance of the electrolyzing process, numerical simulation for electric fields will be conducted by using COMSOL Multiphysics software. Taguchi methods was also used to obtain better ...
