Chiral surface plasmon polaritons on metallic nanowires

S. Zhang
Institute of Physics CAS
Beijing
China

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate. En savoir plus

Magnetic Heating of Iron Oxide Nanoparticles with Alternating Magnetic Field for Hyperthermia Applications

N. M. Sundaram[1], M. Sneha[1], R. S. Vishnu[1], M. Alagappan[1]
[1]PSG College of Technology Coimbatore, Tamil Nadu, India

The current therapies available to treat cancer patients are surgical operation and chemo therapy. The drawbacks are the side effects caused by these therapies. Hyperthermia is a treatment technique based on deactivation of cancer cells by raising the temperature in the range of 43 ºC ... En savoir plus

RF Hot-Zone Location within Rectangular Confined Spaces

R. Rodriguez[1]
[1]University of the West Indies, St. Augustine, Trinidad and Tobago

RF propagation modelling in (30 – 1000 MHz) SAR region for predicting the location and intensities of constructive interference patterns within rectangular confined spaces using waveguide theory and ray tracing techniques. En savoir plus

Study of Hard-and Soft- Magnetorheological Elastomers (MRE’s) Actuation Capabilities

J. Roche[1], P. Von Lockette[1], and S. Lofland[2]
[1]Mechanical Engineering Dept., Rowan University, Glassboro, NJ
[2]Physics and Astronomy Dept., Rowan University, Glassboro, NJ

In this study, magneto-rheological elastomer (MRE) composite beams made of Barium hexaferrite (BaM) and Iron (Fe) powders combined with a highly-compliant matrix material were simulated using COMSOL\'s Solid Mechanics and AC/DC modules. The goal of the work was to develop models capable ... En savoir plus

An All-Purpose Full-Vectorial Finite Element Model for Arbitrarily Shaped Crossed-Gratings

G. Demésy[1], F. Zolla[1], A. Nicolet[1], and M. Commandré[1]
[1]Institut Fresnel, Université Aix-Marseille III, École Centrale de Marseille, France

We demonstrate the accuracy of the Finite Element Method (FEM) to characterize an arbitrarily shaped crossed-grating in a multilayered stack illuminated by an arbitrarily polarized plane wave under oblique incidence. To our knowledge, this is the first time that 3D diffraction ... En savoir plus

Design and Simulation of A MEMS Based Horseshoe Shaped Low Current Lorentz Deformable Mirror (LCL-DM)

B. Park [1], T. Chen [1], C. Shafai [1],
[1] Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, MB, Canada

This poster presents the design and analysis of a novel horseshoe shaped MEMS actuator for adaptive optics. The actuation mechanism is Lorentz force enabling low current (below 10 mA) operation. The actuator combined with an overlying aluminum coated SU-8 soft polymer membrane for the ... En savoir plus

Maximizing Wireless Power Transfer Using Ferrite Rods within Telemetric Devices for Rodents

B. M. Badr [1], R. Somogyi-Csizmazia [1], K. R. Delaney [1], N. Dechev [1],
[1] Department of Mechanical Engineering, University of Victoria, Victoria, BC, Canada

A number of medical and research applications require implantable devices to locally stimulate internal organs and communicate the internal vital signals to the outer world. Wireless power transfer (WPT) technique is used to supply power to these devices. The power is transferred ... En savoir plus

Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

A. Bahrami[1], D. K. Aidun[1]
[1]MAE Department, Clarkson University, Potsdam, NY, USA

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...

COMSOL Multiphysics in Earth Science Education and Research

Dr. R.N. Singh
INSA, Andhra Pradesh, Hyderabad, India

Dr. R. N Singh is currently a INSA Senior Scientist. Prior to this appointment, he was a CSIR Emeritus Scientist at the National Geophysical Research Institute (NGRI), Hyderabad. He has been the Scientist-in-Charge of CSIR Centre of Mathematical Modeling and Computer Simulation, ... En savoir plus

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. ... En savoir plus
