Steady-State and Transient Electrothermal Simulation of Microheater for Gas Sensing

A. N. Radwan [1], M. Mehregany [1],
[1] Case Western Reserve University, Cleveland, OH, USA

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...

COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes

J. Bush [1],
[1] Old Dominion University, Norfolk, VA, USA

The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... En savoir plus

Influence of the Excitation Frequency Increase up to 140 MHz on the VHF-PECVD Technology

S. Leszczynski[1], B. Leszczynska[1], M. Albert[1], J.W. Bartha[1], U. Stephan[2], J. Kuske[2]
[1]Dresden University of Technology, Semiconductor and Microsystems Technology Laboratory, Dresden, Germany
[2]Forschungs- und Applikationslabor Plasmatechnik GmbH, Dresden, Germany

The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase ... En savoir plus

An MHD Study of the Behavior of an Electrolyte Solution Using 3D Numerical Simulation

L. P. Aoki[1], H. E. Schulz[1], M. G. Maunsell[1]
[1]University of São Paulo, São Carlos, SP, Brazil

This article considers a closed water circuit with square cross section filled with an electrolyte fluid. The conductor fluid was moved using an electromagnetic pump, in which a permanent magnet generates a magnetic field and electrodes generate the electric field in the flow. Thus, the ...

Finite Element Analysis of Photoacoustic Response from Gold Nanoparticle

Y. Davletshin[1], J. C. Kumaradas[1]
[1]Ryerson University, Toronto, ON, Canada

Photoacoustic (PA) imaging has matured into a clinical modality for tissue imaging and functional cancer cell research. It uses a pulsed laser to irradiate a region and generate a thermally-induced acoustic pressure wave that can be collected by an ultrasound transducer. The optical ... En savoir plus

An Efficient Finite Element Analysis on an RF Structure Used to Evaluate the Effect of Microwave Radiation on Uveal Melanoma Cells

A. Dulipovici[1], D. Roman[2], I. Stiharu[2], and V. Nerguizian[1]

[1]École de technologie supérieure, Montreal, Quebec, Canada
[2]Concordia University, Montreal, Quebec, Canada

The use of Microwave/RF energy on cancer cells is explored for tumor ablation using medium power level ranging between a few Watts to about 50 Watts. In this research, low power levels, less than 100 mWatt, are used to evaluate the effect of this energy on Uveal melanoma cells by ... En savoir plus

Analysis of a Plasma-Mediated Photoacoustic Response From Plasmonic Nanoparticles in Ultrashort Regime

A. Hatef [1], B. Darvish [1], A. Dagallier [2], C. Boutopoulos [2], M. Meunier [2],
[1] Nipissing University, North Bay, ON, Canada
[2] École Polytechnique de Montréal, Montréal, QC, Canada

Over the last decade, plasmonic nanoparticles (PNPs) have received growing interest as exogenous contrast agents in the thermal expansion based photoacoustic (PA) imaging technique in biomedical applications [1]. Such functionality is due to the localized surface plasmon resonance (LSPR) ... En savoir plus

Electrohydrodynamic Micropump Modeling for Performance Optimization

A. Mulye[1], S. Potnis[2]
[1]Northeastern University, Boston, MA, USA
[2]VIT, Mumbai, Maharashtra, India

We present an optimized and efficient design of an electrohydrodynamic (EHD) micropump for high performance in microscale and biological applications. We are targeting two major applications, a parylene C design for electrically-actuated medicine delivery, and a silicon-based pump design ... En savoir plus

Photonic/Plasmonic Structures from Metallic Nanoparticles in a Glass Matrix

O. Kiriyenko, W. Hergert, S. Wackerow, M. Beleites, and H. Graener
Inst. für Physik, Martin-Luther-Universität Halle-Wittenberg, Germany

Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... En savoir plus

Accuracy of Fully Coupled Loudspeaker Simulation Using COMSOL

M. Hedges[1][2] and Y.W. Lam[1]
[1]Acoustics Research Centre, School of Computing, Science & Engineering, University of Salford, Salford, United Kingdom
