COMSOL Multiphysics® Software and PV: A Unified Platform for Numerical Simulation of Solar Cells and Modules

M. Nardone [1],
[1] Bowling Green State University, Bowling Green, OH, USA

Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality [3]. PV researchers need an accessible and versatile simulation tool to optimize existing ... Read More

Modeling of Rotating Magnetic Field Eddy Current Probe for Inspection of Tubular Metallic Components

T. V. Shyam[1], B. S. V. G. Sharma[1], K. Madhusoodanan[1]
[1]Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised ... Read More

COMSOL Multiphysics® Modelling for Li-ion Battery Ageing

P. Singh[1], N. Khare[2], P. K. Chaturvedi[3]
[1]Banasthali University, Banasthali, Rajasthan, India
[2]EOS Energy Storage, Edison, NJ, USA
[3]SRM University, Ghaziabad, Uttar Pardesh, India

Introduction: Recently, Li-ion battery is being widely used as power source for various applications from electronic gadgets to automotive industry. The performance and cycle life of Li-ion battery are becoming gradually important issues as the applications are shifting from small scale ... Read More

Dispersion Analysis in Coaxial Cables at High Frequencies

S. C. Hegde[1]
[1]VIT University, Vellore, Tamil Nadu, India

The coaxial cable is one of the most commonly used bandwidth limited signal transmission line.Dispersion is a signal distortion phenomenon which arises due to frequency dependence of phase velocity of signal components. This phenomenon was explained through time domain approach by ... Read More

Trapping DNA Molecules in Fluids Using Electrokinetic Effects Generated by Different Electrode Geometries

S. Ghonge[1], S. Kapur [1], S. Banerjee[1]
[1]Birla Institute of Technology and Science, Pilani - Hyderabad Campus, Hyderabad, Telangana, India

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of ... Read More

Some Commonly Neglected Issues Which Affect DEP Applications

G. Zhang[1], V. Pandian[1], J. Brcka[2], J. Faguet[2], E. Lee[2]
[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

Dielectrophoresis (or DEP) has been exploited for various micro and nano fluidics applications like patterning, sorting and separation. However, there are several commonly neglected issues in quantifying DEP forces. Such negligence could potentially lead to wrong DEP force predictions ... Read More

Analysis of Dielectrophoretic Force by Using COMSOL

Taewoo Lee[1]
[1]Department of Biomedical Engineering, Yonsei University, Seoul, South Korea

Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap ... Read More

Elucidating the Mechanism Governing the Cell Rotation Behavior Under DEP

G. Zhang[1], Y. Zhao[1], J. Brcka[2], J. Faguet[2], E. Lee[2]
[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the ... Read More

Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

G. Zhang[1], Y. Zhao[1]
[1]Clemson University, Clemson, SC, USA

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection ... Read More

Effect of Electrical Field Distortion on Particle-Particle Interaction Under DEP

G. Zhang[1], Y. Zhao[1], J. Hodge[1], J. Brcka[2], J. Faguet[2], E. Lee[2]
[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

In using DEP for particle manipulation, researchers often use a formula to calculate the DEP forces in which the forces are proportional to the particle radius to the third power. This formula assumes that the electrical field, E, will not be affected by the presence of a particle, no ... Read More
