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

D.A. Sanz Becerra[1], E.A. Unigarro Calpa[1], J. Osma[1], F. Segura[1]
[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

$Modeling Light Diffraction Using the Finite Element COMSOL$

Modeling Light Diffraction Using the Finite Element COMSOL

J.D. Bamonte
U.S. Naval Academy, Annapolis, MD, USA

COMSOL is finite element modeling software capable of solving partial differential equations. This capability allows for the modeling of boundary value problems, which is necessary to the study of light and the properties of light propagation. For this study, we are modeling Fraunhofer ...

MultiPhysics Analysis of Trapped Field in Multi-Layer YBCO Plates

P. Masson[1], and R. Meinke[1]
[1]Advanced Magnet Lab, Palm Bay, Florida, USA

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous ... 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

Multiphysics Modelling of a Micro Valve

F. Bircher[1] and P. Marmet[1]

[1]Institute of Print Technology, Bern University of Applied Sciences, Burgdorf, Switzerland

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... En savoir plus

Particle Flow Control by Magnetically Induced Dynamics of Particle Interactions

F. Wittbracht[1], A. Weddemann[1], A. Auge[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... En savoir plus

The Optical Properties of a Truncated Spherical Cavity Embedded in Gold

A. Pors[1], O. Albrektsen[2], S.I. Bozhevolnyi[2], and M. Willatzen[1]
[1]Mads Clausen Institute, University of Southern Denmark, Sønderborg, Denmark
[2]Institute of Sensors, Signals and Electrotechnics, University of Southern Denmark, Odense, Denmark

The use of plasmonic effects to dramatically enhance the electromagnetic field near the surface of a metallic nanostructured surface has grown into a large research area in the effort to take advantage of the surface enhanced field. In this paper the electromagnetic field near a nano ... En savoir plus
