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 ... En savoir plus
Electromagnetic metamaterials present exotic and unusual properties hardly to be found in nature with many potential applications. They are usually built by distributing small resonant structures in periodical lattices. If the structure has chiral symmetry, the medium is called chiral ... En savoir plus
Currently there is much interest in electromagnetic metamaterials [1-9]. In our work we have focused on design of tunable metamaterial which can be made within available technology. In proposed design we use metallic split-ring resonators and thin-wires (Figure 1). Moreover we have ... En savoir plus
The electron beam emitted backward by Plasma Focus devices is being investigated as a radiation source for IORT (Intra-Operative Radiation Therapy) applications. A Plasma Focus device is being developed to this aim. The electron beam is driven through an electron pipe made of stainless ... En savoir plus
The resonance conditions for surface plasmons are influenced by the type and amount of material on a surface. Full insight into surface plasmon resonance requires quantum mechanics considerations. However, it can be also described in terms of classical electromagnetic theory by ... En savoir plus
We report here on the use of the COMSOL emw (electromagnetic waves) module in the design of a microwave launcher. This launcher is to be used in a microwave Doppler sensor that is incorporated into a chemical looping combustion system. The launcher is designed in two steps. First, we ... En savoir plus
A wireless passive pressure sensor and the measurement system were design and simulated using COMSOL 4.3. The sensor is based on MEMS capacitor attached to a planar inductor for wireless powering and readout. An external coil is used for the measuring system. The pressure to be measured ...

A piezoelectric transformer allows purely mechanical transfer and scaling of electrical energy via simultaneous utilization of both the direct and converse piezoelectric effects. This mechanical energy transfer enables a wide range of functional differences from typical magnetic-based ... En savoir plus
A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... En savoir plus
Marco Cati graduated cum laude and encomium citation in electronic engineering in 2001 from the University of Florence, where in 2005 he also received a Ph. D. degree in electronic engineering. In 2005 he joined the Research & Development Department of Esaote where he is currently in ... En savoir plus
