Terahertz Resonant Dipole Nanoantennas

S. Tuccio [1], A. Alabastri[1], L. Razzari[1], A. Toma[1], C. Liberale[1], R. Proietti Zaccaria[1], F. De Angelis[1], G. Das[1], E. di Fabrizio[1]
[1]Istituto Italiano di Tecnologia, Genova, Italy

Nanoantennas have been successfully employed in a wide set of applications. We show the possibility to expand usual nanoantenna functionalities in the THz domain with a gold dipole nanoantenna. We considered an array of aligned planar gold nanoantennas over a silicon substrate. The high ... En savoir plus

Topographic Effects on Radio Magnetotelluric Simulations on Levees: Numerical Modeling for Future Comparison With Fields Results

R. Duval[1], C. Fauchard[1], R. Antoine[1]
[1]ERA23-IFSTTAR, Laboratoire des Ponts et Chaussées de Rouen, CETE-Normandie Centre, France

We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered ... En savoir plus

Modeling Microwave Chiral Material Based On Crank Resonators Arrays Using COMSOL Multiphysics

J. Muñoz[1], G.J. Molina [1], M.M. Rojo[1]
[1]Dpto. Electromanetismo y Electrónica, Facultad de Química, Universidad de Murcia, Campus Espinardo, Murcia, Spain

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

FEM Based Design and Simulation Tool for MRI Birdcage Coils Including Eigenfrequency Analysis

N. Gurler[1], Y. Ziya Ider[1]
[1]Department of Electrical and Electronics Engineering, Bilkent University, Ankara, Turkey

Designing a Radio Frequency (RF) birdcage coil used in Magnetic Resonance Imaging (MRI) at high frequencies where the wavelength is comparable with the coil dimensions is a challenging task. Before construction of the coil, not only calculating the capacitance value which is necessary ... En savoir plus

Calculating the Haze Parameter of Textured Transparent Conductive Oxides

A. ?ampa[1], M. Topi?[1]
[1]University of Ljubljana, Faculty of Electrical Engineering, Ljubljana, Slovenia

In thin-film solar cells (a-Si:H, µc-Si:H, CIGS, etc.) scattering of light is very important to increase absorption of light in the active layers of solar cells. Today the most efficient thin-film solar cells are designed or deposited on random textured transparent conductive oxides ... En savoir plus

Microwave Inactivation of Bacteria Under Dynamic Heating Conditions in Solid Media

S. Curet[1], M. Mazen Hamoud-Agha[1]
[1]GEPEA, UMR 6144, CNRS, ONIRIS, Université de Nantes, Nantes, France

In this study, COMSOL®4.2a is used to model a microwave heating process in a TE10 rectangular waveguide. The sample consists of a small cylindrical Ca-alginate gel (D = 8 mm, H = 10 mm) inoculated with bacteria Escherichia Coli K12. The sample is placed along the microwave propagation ...

Design of a Stealth Antenna Using COMSOL Multiphysics

F. De Vita[1], S. Di Marco[1], F. Costa[1], P. Turchi[1]
[1]Altran Italia, Pisa, Italy

This paper will describe some applications of COMSOL Multiphysics to the analysis of Frequency Selective Surface (FSS) structures. Particular attention will be devoted to the possibility of designing a stealthy antenna using the FSS structure. In fact, since it possesses a dual filter ... En savoir plus

Electrical and Thermal Analysis of an OLED Module

J. Kundrata[1], A. Baric[1]
[1]Faculty of Electrical Engineering and Computing, University of Zagreb, Zagreb, Croatia

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED tile and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and its inductor is embedded in the the backplane. The DC ... En savoir plus
