Numerical Analysis of Star-Shaped Nanostructures as Optical Detectors

R. Diaz de Leon-Zapata¹, J. V. González-Fernández¹, A. B. de la Rosa-Zapata¹, E. Flores-García¹, J. Sanchez², J. Gonzalez²
¹Tecnologico Nacional de Mexico/ITSLP, Mexico
²UASLP, San Luis Potosí, Mexico

With the use of COMSOL Multiphysics®, a full characterization of star shaped geometry structures of silver-zinc oxide (Ag-ZnO-Au) study is presented. Analysis with different thicknesses of gold cover, as well as with different lengths and additional arrangements of the structure have ... En savoir plus

Multiphysics Analysis of a Micromirror System

N. Katte[1]
[1]Wilberforce University, USA

The challenge of our current research is to design large aperture MEMS scanning mirrors for Light Detection and Ranging (LIDAR) applications such as in unmanned driving or Unmanned Aerial Vehicle. The current MEMS scanning mirrors have a smaller aperture which limits application, it can ... En savoir plus

Full-Wave Simulation of an Optofluidic Transmission-Mode Biosensor

E. P. Furlani[1], N. M. Litchinitse[2], and R. Biswas[2]

[1]The Institute for Lasers, Photonics and Biophotonics, University at Buffalo, Buffalo, New York, USA
[2]Department of Electrical Engineering, The State University of New York at Buffalo,Buffalo, New York, USA

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... En savoir plus

Model Time Step Consideration for Modeling Electron Drift in Argon and Helium

D. McCormick[1]
[1]BHGE, USA

For many decades Helium-3 (3He) and Argon gas filled detectors have been used for neutron and gamma detection. Detection requires the generation of electrons which can then be measured by electronic means. These electrons are generated either directly through gamma ionization of a gas ... En savoir plus

Finite Element Modeling of Transient Eddy Currents in Multilayer Aluminum Structures

V. Babbar[1], and T. Krause[1]

[1]Department of Physics, Royal Military College of Canada, Kingston, Ontario, Canada

Transient eddy current (TEC) technique is being developed for detection of flaws located at depth within multilayer aluminum structures. The present work involves finite element modeling using COMSOL Multiphysics software to simulate different types of probes by changing some of these ... En savoir plus

Electrical Impedance Sensor to Detect Tunnels and Infrastructure in Soil

R. Gamache, and D. Spinelli
TransTech Systems, Inc., Schenectady, NY, USA

Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as ...

Optimization of Microfabricated 2D Planar Spiral Microcoils for the Micro NDT of Grinding Burn

Isman Khazi¹, Andras Kovacs¹, Rui Zhu¹, Ulrich Mescheder¹
¹Institute for Microsystem Technology(iMST), Furtwangen University, 78120 Furtwangen, Germany

Cylindrical grinding has become an integral part of machining of workpieces with an ultra-high precision and higher throughput. The grinding process involves the mechanical interaction of the grinding blade with the workpiece at relatively higher rotation speeds, with a higher energy ... En savoir plus

Design of a Nucleic Acid Biosensor Using COMSOL Multiphysics®

L. Velmanickam [1], D. Nawarathna [1], V. Jayasooriya [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

Cancer is one of the leading causes of deaths worldwide. According to the American Cancer Society, there will be about 700,000 cancer related deaths in US in 2017. Cancer mortality will be reduced if it is detected and treated at the early stages. Previous studies have shown that ... En savoir plus

Effect of Antennae Polarization Relative to Tunnel Orientation on Electromagnetic Wave Scattering due to Underground Tunnels

A. Farid[1], and T. Raza[1]
[1]Civil Engineering, Boise State University, Boise, Idaho, USA

Illegal immigrants and smugglers frequently use underground tunnels to avoid border security and checkpoints. In addition, the threat of international terrorism has recently made the effort to detect tunnels a national security priority. No single technology and sensing modality is ... En savoir plus

Development and Characterization of High Frequency Bulk Mode Resonators

H. Pakdast, Z. Davis
DTU Nanotech, Technical University of Denmark, Kgs. Lyngby, Denmark

This article describes the development of a bulk mode resonator which can be employed for detection of bio/chemical species in liquids.
