An Efficient Finite Element Analysis on an RF Structure Used to Evaluate the Effect of Microwave Radiation on Uveal Melanoma Cells

A. Dulipovici[1], D. Roman[2], I. Stiharu[2], and V. Nerguizian[1]

[1]École de technologie supérieure, Montreal, Quebec, Canada
[2]Concordia University, Montreal, Quebec, Canada

The use of Microwave/RF energy on cancer cells is explored for tumor ablation using medium power level ranging between a few Watts to about 50 Watts. In this research, low power levels, less than 100 mWatt, are used to evaluate the effect of this energy on Uveal melanoma cells by ... Read More

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 ... Read More

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 ...

Numerical 3D-FEM-simulation Made By COMSOL Multiphysics of a Microwave Assisted Cleaning System for a Diesel Sooty Particle Filter and its Experimental Validation

I. Imenokhoyev, A. Matthes, H. Gutte, and G. Walter
TU Bergakademie Freiberg
Freiberg, Germany

By means of a numerical 3D-FEM-simulation, some alternatives for the arrangement of the waveguide supplying the microwave energy to a cylindrical ceramic filter are investigated. The different alternatives are compared concerning a homogenous distribution of the electromagnetic field and ... Read More

Electroplating is a vital technology widely employed for many technological applications ranging from decorative or anti-corrosion coatings to high precision nanotechnology passive electromagnetic cloaking devices. This 2D Axisymmetric Electroplating Model demonstrates one of the ... Read More

Electric Field Distributions and Energy Transfer in Waveguide-Based Axial-Type Microwave Plasma Source

H. Nowakowska[1], M. Jasínski[1], and J. Mizeraczyk[1,2]
[1]The Szewalski Institute of Fluid-Flow Machinery, Polish Academy of Sciences, Gdansk, Poland
[2]Dept. of Marine Electronics, Gdynia Maritime University, Gdynia, Poland

In this paper, we examine changes of the electric field distributions in waveguide-based axial-type microwave plasma source (MPS) during tuning procedure. The distributions strongly depend on position of the movable short, so does the wave reflection coefficient of the incident wave. A ... Read More

Time-Harmonic Modeling of Squirrel-Cage Induction Motors: A Circuit-Field Coupled Approach

R. Escarela-Perez[1], E. Melgoza[2], and E. Campero-Littlewood[1]

[1]Universidad Autonoma Metropolitana - Azcapotzalco, Departamento de Energia, México, D.F., Mexico
[2]Instituto Tecnologico de Morelia, Morelia, Mich., C.P., Mexico

Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... Read More

Electrode-Electrolyte Interface Simulation in Microbubble Distillation: Role of (DDLs) as Electrochemical Cell

M. Mohammed[1]
[1]University of Sheffield, United Kingdom

The proposed dielectric mediums of a hot microbubble interface experience different behaviors due to the electrical mobility of carriers (electron and ion) within their domains. The responses of such mediums towards the initial and average mobility of these carriers can be classified as ... Read More
