Shielding Cylinder Effect in High-Speed Electric Machines

B. Hannon[1], P. Sergeant[1]
[1]Ghent University, Ghent, Belgium

In the field of electric machines, a trend towards both higher efficiency and higher power density is observed. This has led to a growing importance of Permanent Magnet Synchronous Machines. However, the magnets used in these machines risk demagnetization at high temperatures. Especially ... Read More

Numerical Analysis and Optimization of a Multi-Mode Interference Based Polarization Beam Splitter

Y. D'Mello [1], E. Elfiky [1], J. Skoric [1], D. Patel [1], D. Plant [1]
[1] McGill University, Montréal, QC, Canada

The progression toward smaller and faster photonic circuits has led to the development of nanophotonic platforms capable of compacting many devices onto an integrated chip. These devices, as well as the input and output grating couplers, are sometimes polarization dependent, which allows ... Read More

Mixing and Residence Time Distribution Studies in Microchannels with Floor Herringbone Structures

A. Cantu-Perez, S. Ping Kee, and A. Gavriilidis
University College London, Department of Chemical Engineering, Torrington Place, London, UK

The mixing characteristics and residence time distributions (RTDs) of a staggered herringbone microchannel have been investigated numerically by COMSOL Multiphysics and by particle tracking algorithms that incorporate diffusion via a random walk. All simulations were validated with ... Read More

Modeling and Simulation of Artificial Core-Shell Based Nanodielectrics for Electrostatic Capacitors Applications

D. Musuwathi Ekanath[1], N. Badi[1], and A. Bensaoula[2]
[1]Center for Advanced Materials, University of Houston, Houston, TX
[2]Dept. of Physics, University of Houston, Houston, TX

The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). ...

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 ... Read More

Structure of a Classical Vortex Ring

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

This talk is for users of the COMSOL Multiphysics® software who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. As part of a multi-year plan to develop proficiency in Equation ... Read More

Lamb Waves in Fluid-Loaded Plates

T. Kaufmann[1], F. Kassubek[1], D. Pape [1], M. Lenner[1]
[1]ABB Corporate Research, Baden-Dättwil, Switzerland

Lamb waves are elastic waves propagating in free solid plates. In the case of plates loaded with a fluid, the equations describing these waves have to be modified to include the effects of the fluid. In our work we have tackled this problem using COMSOL Multiphysics®. We have used the ... Read More

Design and Optimization of an All Optically Driven Phase Correction MEMS Deformable Mirror Device using Finite Element Analysis

V. Mathur[1], K. Anglin[1], V.S. Prasher[1], K. Termkoa[1], S.R. Vangala[1], X. Qian[1], J. Sherwood[1], W.D. Goodhue[1], B. Haji-Saeed[2], and J. Khoury[2]

[1]Photonics Center, University of Massachusetts-Lowell, Lowell, Massachusetts, USA
[2]Air Force Research Laboratory/Sensors Directorate, Hanscom Air Force Base, Massachusetts, USA

Optically addressable MEMS mirrors are required for future high density adaptive optics array systems. We have demonstrated a novel technique of achieving this by actuating low stress Silicon Nitride micro mirrors via cascaded wafer bonded Gallium Arsenide photo detectors on Gallium ... Read More

Software Package for Modeling III-Nitride QW Laser Diodes and Light Emitting Devices

M. V. Kisin[1], R. G. W. Brown[1], and H. S. El-Ghoroury[1]
[1]Ostendo Technologies, Inc., Carlsbad, CA, USA

We present a modeling software package developed at Ostendo Technologies for analysis and design of semiconductor laser and light-emitting diodes. The current database of material parameters supports complete group of III-Nitride alloys used in visible spectrum applications and can be ... Read More

Benard-Rayleigh convection in thin ring layer

A. Fedotov¹, Y. Tsitavets¹, Y. Levy²
¹Belarusian State University, Minsk, Belarus
²HiLASE Centre, Prague, Czech Republic

Convective instability in a thin liquid layer is observed in many technical systems [1] and is of interest to the self-organization theory. To date, however, only simple problems with the convection between flat plates are well studied [2]. In real systems and devices, convective flows ... Read More
