Computing Surface Acoustic Wave Dispersion and Band Gaps

R. Westafer [1], S. Mohammadi [1], A. Adibi [1], W. Hunt [1]
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

The dispersion of surface acoustic waves (SAWs) has long been studied for diverse applications ranging from seismic waves to microelectronic filters. In this work, we apply COMSOL Multiphysics software for the finite element investigation of SAW dispersion in two inhomogeneous ... Read More

Modeling Optical Nanoantenna Arrays with COMSOL Multiphysics

Z. Liu[1], X. Ni[1], and A. Kildishev[1]
[1]School of Electrical and Computer Engineering and Birck Nanotechnology Center, Purdue University, West Lafayette, Indiana, USA

Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. Such enhanced local fields have many applications such as ... Read More

TM Wave Propagation in Optical Nanostructures with a Third-Order Nonlinear Response: Modeling and Validation with COMSOL

A. Kildishev[1], E. E. Narimanov[1]
[1]Birck Nanotechnology Center, School of Electrical and Computer Engineering, Purdue University, West Lafayette, Indiana, USA

An enhanced method is used for analysis of third-order nonlinearities in optical nanostructures with scalar TM (H-field) frequency domain formulation. After embedding it in COMSOL Multiphysics it is shown to produce fast and accurate results without superfluous vector E-field formalism. ... Read More

Measuring the Spectra of Metamaterials at an Oblique Incidence

X. Ni[1,2], Z. Liu[1,2], and A.V. Kildishev[1,2]
[1]School of Electrical and Computer Engineering, Purdue University, West Lafayette, Indiana, USA
[2]Birck Nanotechnology Center, Purdue University, West Lafayette, Indiana, USA

The emergence of electromagnetic metamaterials has given rise to a variety of fascinating applications, including the perfect lens and the optical cloaking device. For a long time the study of the properties of metamaterials was limited to normal incidence only. However, it is extremely ... Read More

Simulations of Scanning Electrochemical Microscopy Experiments in Pure Negative and Positive Feedback Mode with Ring Microelectrodes

J. Mauzeroll[1], M. Mayoral[1], and D. Fabre[1]
[1]Department of Chemistry, Université du Québec à Montréal, Montreal, Quebec, Canada

Scanning electrochemical microscopy (SECM) is a powerful tool recently developed for studying structures and processes in micrometer and submicrometer sized systems. It can probe electron, ion, and molecule transfers, and other reactions at solid-liquid, and liquid-liquid, interfaces . ... Read More

COMSOL Derived Universal Scaling Model For Low Reynolds Number Viscous Flow Through Microfabricated Pillars – Applications to Heat Pipe Technology

N. Srivastava[1], and C.D. Meinhart[1]
[1]Department of Mechanical Engineering, University of California Santa Barbara, Santa Barbara California, USA

Cooling of high-power density electronic devices remains a challenge. Microfluidic heat-pipes with the potential of achieving ultra-high thermal conductivities offer a low-cost technology for cooling electronics. To achieve high thermal conductivity, it is critical to maximize the rate ... Read More

Modeling of Drying of Cellular Ceramic Structures: Coupled Electromagnetic and Multiphase Porous Media Model

A. Dhall[1], G. Peng[2], G. Squier[2], M. Geremew[3], L. Bogaczyk[2], J. George[3], W.A. Wood[3], and A.K. Datta[1]
[1]Biological and Environmental Engineering, Cornell University, Ithaca, New York, USA
[2]Manufacturing Technology & Engineering, Corning Inc., Sullivan Park, Corning, New York, USA
[3]Corporate Research, Corning Inc., Sullivan Park, Corning, New York, USA

Cellular ceramic substrates are extensively used for pollution control systems in vehicles. The manufacturing process of them can involve microwave drying. In this study, we describe the development of a modeling framework for the microwave drying process of these substrates. The ... Read More

Modeling the Collimator-Detector Scattering Using Stochastic Differential Equations and COMSOL

A. Jeremic[1], T. Farncombe[2], S. Liu[2], and Y. Abdul-Rehman[1]
[1]Department of Electrical and Computer Engineering, McMaster University, Hamilton, Ontario, Canada
[2]Department of Radiology, McMaster University, Hamilton, Ontario, Canada

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular ... Read More

A Study of Curved Flexures for MEMS

Minhee Jun[1], and Jason V. Clark[1]
[1]Departments of Electrical and Computer Engineering, Purdue University, West Lafayette, IN, USA

Large deflection actuators are becoming increasingly important for microsystems. Since actuation forces are usually small, large deflection actuators usually require flexures with low stiffness. Rectangular serpentine flexures are often used for such actuators due to their low stiffness ... Read More

Two-dimensional Analysis of Triple Coupled Physics of Structural Mechanics, Diffusion and Heat Transfer in a Gas Pipe

P. Lee-Sullivan[1], and M. Haghighi-Yazdi[1]
[1]Department of Mechanical and Mechatronics Engineering, University of Waterloo, Waterloo, Ontario, Canada

In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary ... Read More
