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. ...

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 ...

In this paper the propagation of a plane wave in a large lossy medium is presented. The investigated geometry consists in a wedgeshaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar technique for measuring the length of the dielectric wedge. In order to address this problem and to evaluate ...

In this paper, we apply COMSOL Multiphysics, a finite element package, to compute the capacitance of a single centered microstrip line and the capacitance and inductance matrices of coupled multistrip lines. We compared our results with those in the literature such as variational technique, method of moments, finite difference method, Green’s function-integral equation technique, and found them ...

In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the disturbing signal inside the system, which is necessary for the following simulation, will be described ...

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.

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate.

Use of the terahertz(THz) region, which is unexplored frequency band, is investigated and expected for the next-generation high-speed wireless communication. In this presentation, we propose a monolithic integrated device by using mesa-shaped compound semiconductor and a thin-metal broadband antenna which is capable in THz operation, and we analyze several characteristics of the device by using ...

Hyperthermia is newly back in the interest of both, clinical and research oncologists, because of its properties to directly produce permanent damages of the treated tumors and to elicit important immunological responses against cancer cells by changing their immunogenicity. Microwave ablation is used in the treatment of primary and secondary tumors of the liver. Microwave antennas ...
