There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors and the associated electronic chips can be generated. This power can be generated using the pressure exerted by ...

The dosimetric analysis of the non-ionizing electromagnetic field (EMF) penetration in exposed biological material requires the existence and monitoring of a controlled testing environment.The practical solution for high frequency EMF exposure is the setting of the experiment in an anechoic chamber, or, more economically, in a TEM cell that is able to provide a reduced testing region with EMF ...
Modeling the Radiation of a Commercial Sensor, the Fish Fat Meter, in a Multilayer Biological Material
Centre INRA de Theix, St Genes Champanelle, France
The Fish Fat Meter sensor is used for in vivo measurement of intramuscular fat content in fishes. It is based on the propagation of a 2 GHz wave along a micro-strip line placed against the fish. It is used at INRA to select fat or lean fish in fish-farming studies. COMSOL Multiphysics has been used to perform 2D and 3D modeling in order to support recommendations to users of the Fish Fat Meter. ...

In order to design an RF MEMS based device, it is beneficial to have information concerning mechanical behavior. For model verification purpose, solution offered by simulation software equipped with predefined physics application is one valuable way to provide initial reference. To avoid unwanted particular total strain in RF MEMS structures, a compensation layer can be utilized. When the number ...

Mit FEMLAB 2.x und 3.1 wurden Voruntersuchungen zu zwei Anwendungen versucht. Im ersten Projekt sollte die Möglichkeit geklärt werden, FEMLAB für die Verhaltenssimulation integrierter ASIC-Photodioden einzusetzen und in der zweiten Anwendung sollten spezielle photonische Kristalle untersucht werden.

University of Padova, Padova, Italy
We present a Finite Element Method (FEM) to calculate the complex valued k(?) dispersion curves of a photonic crystal slab in presence of both dispersive and lossy materials. In particular the method can be exploited to study plasmonic crystal slabs. We adopt Perfectly Matched Layers (PMLs) in order to truncate the open boundaries of the model, including their related anisotropic permittivity and ...

We are studying the ability of subresolution optical structures to store data. We begin our study with surface relief structures. Because we are probing features whose sizes are much smaller than the wavelength of the readout light, retrieval of data from these structures requires near-field detection. The dimensions of the glass fill-in and the grooves of the above mentioned structure was ...

In this paper, COMSOL Multiphysics software is utilized as a finite element forward solver to obtain the electromagnetic fields at the receiving antennas while the breast is illuminated by one antenna in the array. Geometry consists of coronal slices of the 3-D breast. Simulations are done by a MATLAB code which runs COMSOL finite element solver and collects the data at the receiving antennas at ...

Normal conducting cavities are typically used in the front end of proton accelerators to get the beam accelerated to velocities approximately a few tenths of the speed of light, where superconducting cavities can then be used to accelerate the beam to the speed of light. The warm part of a typical proton accelerator would contain a radio frequency quadrupole (RFQ) and several buncher cavities. ...

In this paper resonances in tapered double-port TEM waveguides are used as benchmark for simulations. FEM simulations with COMSOL Multiphysics® and simulations using generalised telegraphist's equations with MATLAB® are compared to ananalytical method capable of calculating the resonances of higher order modes. It is valid for tapered double-port TEM waveguides with constant ...
