Modeling and Experimental Verification of the Power Transfer and Thermal Characteristics of Piezoelectric Transformers Subjected to Combined Mechanical and Electrical Loading

S. Tuncdemir[1], W.M. Bradley[2]
[1]Solid State Ceramics, Williamsport, PA, USA
[2]QorTek, Williamsport, PA, USA

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

Passive Microsensor Based on LC Resonators for Substance Identification

[1]Universidad de los Andes, Bogotá, Colombia

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

Air Gap Field Analysis of Single Sided Linear Induction Motor With Time-Harmonic Finite Element Method

M.S. Manna[1], S Marwaha[1], and N. Kaur[2]
[1]Dept. of EIE, Sant Longowal Inst. of Engg. & Tech Longowal, Sangrur, Punjab, India
[2]Dept. of ECE, Universal Group on Institutes, Lalaru, Punjab, India

In recent years, the single-sided linear induction motor (SLIM) has been the most suitable choice for electric vehicles of the wheel and touchless type. The reason is simplicity in manufacturing, capability in applying direct force, moving and braking and low pollution. To study the ... En savoir plus

Simulation of Microwave Heating of Porous Media Coupled with Heat, Mass and Momentum Transfer

J. Subbiah[1], J. Chen[1], K. Pitchai[1], S. Birla[1], D. Jones[1]
[1]University of Nebraska, Lincoln, NE, USA

A microwave heating model coupled with heat, mass, and momentum transfer is needed to fully understand the microwave heating process. In this study a comprehensive 3D model was developed for studying the interaction of microwave with the food. The model includes physics of Maxwell’s ... En savoir plus

Bayesian Estimation of Tumors in Breasts Using Microwave Imaging

A. Jeremic[1], E. Khosrowshahli[1]
[1]McMaster University, Hamilton, ON, Canada

Although mammography is extremely important diagnostic technique, it suffers from some limitations such as false negative and positive results, using ionizing radiation and patient’s discomfort. Microwave imaging has been recently proposed as an additional medical imaging technique ... 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

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

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

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 ... En savoir plus

FE Modeling of Surfaces with Realistic 3D Roughness: Roughness Effects in Optics of Plasmonic Nanoantennas

J. Borneman[1], A. Kildishev[1], K. Chen[1], and V. Drachev[1]

[1]School of Electrical and Computer Engineering and Birck Nanotechnology Center, Purdue University, West Lafayette, Indiana, USA

COMSOL Multiphysics has been widely used to model the near and far-field electromagnetics (specifically, transmission and reflection spectra) of gold and silver nanoantenna arrays. We use a moving 3D mesh, thus preserving the DOF number and simply morphing the structure of the mesh ... En savoir plus
