Contactless Power and Data Transfer for Multiple Nonlinear Loads

H.P. Schmidt [1], U. Vogl[1]
[1]UAS HAW Amberg-Weiden, Amberg, Germany

For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra ... En savoir plus

Modeling of a Nonlinear Hybrid Plasmonic Waveguide for Enhanced Surface Plasmon Polaritons Through Optical Parametric Amplification

D. Wang[1], T. Li[1], S. Wang[1], S. Zhu[1]
[1]Nanjing University, Nanjing, Jiangsu, China

Surface Plasmon Polaritions (SPPs), as electromagnetic waves localized at the surface of a metal, enjoy the unique properties to confine energy into sub-wavelength scale, which is beneficial for future photonic integration. However, the severe absorption caused by the metal influences ... En savoir plus

High Frequency Magnetohydrodynamic Calculations in COMSOL

N. Kleinknecht, and S. A. Halvorsen
Teknova AS
Kristiansand, Norway

In many metallurgical processes metals are (heated and) stirred by an oscillating external magnetic field. The magnetic field induces electric currents in the metal and the currents interact with the magnetic field to create a force, the Lorentz force. For high frequencies induction only ...

Laminar Fluid Flow and Heat Transfer Studies of an Electrical Conducting Fluid Subject to Combined Electric and Magnetic Fields

E. Gutierrez-Miravete[1], T. DePuy[2], and X. Xie[2]
[1]Rensselaer at Hartford, Hartford, CT
[2]Pratt & Whitney, East Hartford, CT

The flow of electrically conducting fluids such as liquid metals is significantly affected by applied electric and magnetic fields. The effect has important industrial applications in metallurgy, nuclear technology and other fields. This paper described results of a series of studies ... En savoir plus

First Approach Toward a Modeling of the Impedance Spectroscopic Behavior of Microbial Living Cells

[4] LEAS, St. Ismier, France
[5] HBA Biotech SA, Grenoble, France

The subject of the interactions between electromagnetic (EM) fields and living cells is a strong issue for several decades [1]. Large number of works have been done to study the EM field penetration and inner induced currents in living microorganisms. Relevant information to be collected ... En savoir plus

Photonic/Plasmonic Structures from Metallic Nanoparticles in a Glass Matrix

O. Kiriyenko, W. Hergert, S. Wackerow, M. Beleites, and H. Graener
Inst. für Physik, Martin-Luther-Universität Halle-Wittenberg, Germany

Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... En savoir plus

Analyzing the Performance of Lined and Unlined Simplified Cylindrical Cloaks

J. McGuirk and P. Collins
Air Force Institute of Technology, WPAFB, OH, USA

The performance of simplified cylindrical cloaks with various material parameters was investigated. The performance metric was the overall scattering width of the cloak with various objects in the hidden region. COMSOL was used to simulate three cloaks with different material parameters ...

Finite Element Modeling of Pulsed Eddy Current Applied to Ferrous and Titanium Fasteners in F/A-18 Airplane Wing Structure

V. K. Babbar[1], P. R. Underhill[1], T. W. Krause[1]
[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

Pulsed eddy current (PEC) is being developed to detect stress corrosion cracks between fasteners on the inner wing spars of the F/A-18 Hornet aircraft. The spars are located below a thick carbon/epoxy wing skin, and so cannot be detected by conventional eddy current techniques without ... En savoir plus

A Reliable Approach to Estimate Surface-enhanced Raman Scattering Intensity of Metal Nanostructures

En-Ming You [1], Jun Yi [1], Song-Yuan Ding [1,2],
[1] State Key Laboratory of Physical Chemistry of Solid Surfaces, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen, China
[2] Collaborative Innovation Center of Chemistry for Energy Materials, Xiamen University, Xiamen, China

Surface-enhanced Raman scattering (SERS) is a fingerprint spectroscopy whose sensitivity is down to single molecule level. The mechanism of SERS is mainly contributed to huge enhancement of local electric field, which originated from surface plasmon resonance of metal nanostructures. It ... En savoir plus

Computational design and analysis of Microwave Tomography in Intracerebral Hemorrhage

Priyadarshini Natarajan [1], Rajkumar ElagiriRamalingam[1]
[1]Division of Biomedical Engineering, School of Biosciences and Technology, VIT University, Tamil Nadu, India

Intracerebral hemorrhage is a condition where a blood vessel in the brain ruptures and causes internal bleeding leading to hemorrhagic stroke. 800 in every 100,000 people suffer from stroke each year and it's one of the major causes of mortality worldwide. Diagnosis involves Neurological ... En savoir plus
