Analysis of Optical Manipulation of a Metallic Nanowire using COMSOL Multiphysics®

Ryota OZAWA et al.[1]

[1]Yokohama National University, Yokohama, Kanagawa, Japan

We have developed optically driven micropumps by manipulating microstructures using optical tweezers. In this study, we proposed and developed a novel manipulation method of a single metallic nanowire. In this method, dynamic optical vortex is used not only for manipulating a metallic ... Mehr lesen

Finite-Element Analysis of High Frequency Electromagnetic Fields

Masanori HASHIGUCHI et al.[1]

[1]Keisoku Engineering System Co., Ltd., Chiyoda City, Tokyo, Japan

Using COMSOL Multiphysics, numerical solution of electromagnetic field of microstrip open stub is obtained in frequency domain of 0.1GHz - 60GHz by using the COMSOL RF Module and the computed S11 is compared to experiment. It was found that the S11 predicted here is in good agreement ... Mehr lesen

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 ... Mehr lesen

Optical Modeling of Organic Solar Cells Using the COMSOL

Jungho Kim[1]
[1]Department of Information Display, Kyung Hee University, Seoul, South Korea

A solar cell offers a potential solution to energy shortage problems by converting sunlight into electrical power. Organic solar cells (OSCs) are low-cost and versatile, but also tend to be low-efficiency and short-lasted. Three macroscopic parameters determine their power-conversion ... Mehr lesen

Demonstration of All-Optical NAND Logic Gate Using Photonic Integrated Circuits

J. T. Andrews[1], R. Choubey[1], O P Choudhary[1], N. Malviya[1], A. Patel[1], M. Kumar[1], S. Chouksey[1], J. Solanki[1]
[1]National MEMS Design Center, Department of Applied Physics, Shri G S Institute of Technology & Science, Indore 452003 MP, India

A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

Joule Heating in Electroosmotically Driven Circular Constriction Microchannel

U. Sanjay [1], P. Sarith[2], R. Ajith Kumar[1]
[1]Amrita Vishwa Vidhyapeetham, Kollam, Kerala, India.
[2]National institute of Technology, Calicut, Kerala, India.

Liquid transport in lab-on-a-chip (LOC) devices occurs through a microchannel that uses an electroosmotic flow actuation mechanism. This method has a plug-like velocity profile, which is ideal in species transport and in wall-bounded reactions. Under substantial joule heating, it is not ... Mehr lesen

Structural Durability Analysis of Powertrain Mounting Bracket

Sameer Kolte[1], David Neihguk[1], Abhinav Prasad[1]
[1]Mahindra and Mahindra Ltd., Vehicle Integration COE, Mahindra Research Valley, Mahindra World City, Chengalpattu, Tamil Nadu, India

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that ... Mehr lesen
