Forces and Heating in Plasmonic Particles

M. Gonçalves[1], O. Marti[1]
[1]Ulm University - Inst. of Experimental Physics, Ulm, Germany

Plasmonic resonances arising in gold nanoparticles lead to strongly localized near-field enhancements. These enhancements generate strong field gradients that can be exploited in particle trapping. On the other hand plasmonic resonances lead to enhanced absorption and heat generation. ... Read More

Surface Plasmon Resonance Dependence on Size in Metallic Nano-Spheres

K. Kluczyk[1], W. Jacak[1]
[1]Institute of Physics, Wrocław University of Technology, Wrocław, Poland

Surface plasmon resonance in metallic nanoparticles is highly and shape dependent, which enables varius applications in photovoltaics, photonics, sensing and even medicine. Particularly we observe redshift in plasmon resonance with increasing nanoparticle size. We investigate ... Read More

Analysis and Design of Antennas for an Implantable Medical Device System for Functional Electrical Stimulation

H. Suri[1]
[1]Alfred Mann Foundation for Scientific Research, Valencia, CA, USA

This poster outlines the results of finite element analyses to study the antenna radiation pattern of an implanted medical device. Also presented are simulation results used to design an electrically small antenna for a portable control unit that communicates with the implants over the ... Read More

Comparison of 2D and 3D FEM Models of Eddy Current Pressure Tube to Calandria Tube Gap Measurement

G. Klein [1], J. Morelli [1], T. Krause [2],
[1] Queen's University, Kingston, ON, Canada
[2] Royal Military College of Canada, Kingston, ON, Canada

Two different Finite Element Method (FEM) models of the CANDU® nuclear fuel channels were compared against experimental data to determine if the curvature of the fuel channels is necessary to consider for measurements of the pressure tube to calandria tube gap. The different models were ... Read More

S. Müller [1], M. Keller [1], A. Echle [1], A. Enssle [1], P. Präg [1], A. Lusiewicz [1], D. Maier [1], N. Parspour [1],
[1] Institute of Eletrical Energy Conversion, University of Stuttgart, Stuttgart, Germany

The paper presents the three dimensional (3D) Finite Element Method (FEM) COMSOL Multiphysics® model of a Three Phase Permanent Magnetic Excited Transverse Flux Machine (TFM). The model is fully parameterized and able to sweep over all parameters during design optimization process. The ... Read More

Development of a Package for a Triaxial High-G Accelerometer Optimized for High Signal Fidelity

R. Langkemper [1], R. Külls [1], J. Wilde [2], S. Nau [1], S. Schopferer [1],
[1] Fraunhofer-Institut für Kurzzeitdynamik, Ernst-Mach-Institut, EMI, Freiburg, Germany
[2] Albert-Ludwigs-Universität Freiburg, Institut für Mikrosystemtechnik, Freiburg, Germany

Acceleration is an important quantity to be measured in high-speed dynamics. A new piezoresistive sensor for the measurement of high-amplitude, short-duration transient accelerations of up to 100,000 g has been developed at the Fraunhofer EMI. Its figure of merit (sensitivity x resonance ... Read More

SAW Sensors for Surgical Arm using Piezoelectric Devices

Rakesh Kumar Pati [1], SK Mohammed ali[1], Sakuntala Mahapatra[1], Millee Panigrahi[1]
[1]MEMS Design Centre, Dept. of ETC, Trident Academy of Technology, Bhubaneswar, Odisha, India

Despite of the existing successful clinical applications, however, the interaction, i.e. artificial sensing, between the robot and the patient is still very limited. With the help of various cameras, vision is almost the only feeling that a robot can have. In order to imitate the human ... Read More
