[1]Department of Orthopaedics, University of Rostock, Rostock, Germany
[2]Department of General Electrical Engineering, University of Rostock, Rostock, Germany

A common clinical treatment is the application of alternating electromagnetic fields using a screw implant to the weak bone tissue within the femoral head, which speed up the bone regeneration in case of avascular necrosis of the femoral head . In our present work the bipolar induction ... Mehr lesen

Design of Precision Magnetic Fields for Fundamental Neutron Symmetries

M. Higginson-Rollins[1], C. Crawford[2]
[1]Department of Electrical & Computer Engineering, University of Kentucky, Lexington, KY, USA
[2]Department of Physics & Astronomy, University of Kentucky, Lexington, KY, USA

The traditionally magnetic design process involves guessing at a reasonable conductor geometry, using finite element analysis (FEA) software to calculate the resulting fields, and modifying the configuration iteratively to reach an acceptable solution. Taking the opposite approach, we ... Mehr lesen

Inverse-Design in Large Photonic Gratings Enabling Efficient Photonic-to-Free-Space Mode Coupling

A. Yulaev¹, D. A. Westly², Vladimir A. Aksyuk²
¹Department of Chemistry and Biochemistry, University of Maryland, College Park, MD, USA
²PML, National Institute of Standards and Technology, Gaithersburg, MD, USA

Realization of an efficient coupling between photonic sub-micrometer size modes and hundred micrometer wide free-space beams remains a main engineering hurdle to a wider acceptance of miniaturized chip-scale atomic and bio systems. The major obstacle comes from a gigantic mode mismatch ... Mehr lesen

An AlGaN/GaN Based UV Photodetector Simulation Using COMSOL® to Obtain the Fresnel Coefficients

B. Uppalapati¹, G. Koley¹, A. Kota²
¹Clemson University, Clemson, SC, USA
²University of Dayton, Dayton, OH, USA

Over the past two decades, extensive research has been conducted on ultraviolet (UV) photodetectors (PDs) because of their potential applications across various fields including military, medicine, environmental monitoring, and deep space explorations. To fabricate solar-blind UV PDs ... Mehr lesen

Influence of the Excitation Frequency Increase up to 140 MHz on the VHF-PECVD Technology

[1]Dresden University of Technology, Semiconductor and Microsystems Technology Laboratory, Dresden, Germany
[2]Forschungs- und Applikationslabor Plasmatechnik GmbH, Dresden, Germany

The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase ... Mehr lesen

An MHD Study of the Behavior of an Electrolyte Solution Using 3D Numerical Simulation

L. P. Aoki[1], H. E. Schulz[1], M. G. Maunsell[1]
[1]University of São Paulo, São Carlos, SP, Brazil

This article considers a closed water circuit with square cross section filled with an electrolyte fluid. The conductor fluid was moved using an electromagnetic pump, in which a permanent magnet generates a magnetic field and electrodes generate the electric field in the flow. Thus, the ... Mehr lesen

Finite Element Analysis of Photoacoustic Response from Gold Nanoparticle

Y. Davletshin[1], J. C. Kumaradas[1]
[1]Ryerson University, Toronto, ON, Canada

Photoacoustic (PA) imaging has matured into a clinical modality for tissue imaging and functional cancer cell research. It uses a pulsed laser to irradiate a region and generate a thermally-induced acoustic pressure wave that can be collected by an ultrasound transducer. The optical ... Mehr lesen

Accuracy of Fully Coupled Loudspeaker Simulation Using COMSOL

M. Hedges[1][2] and Y.W. Lam[1]
[1]Acoustics Research Centre, School of Computing, Science & Engineering, University of Salford, Salford, United Kingdom
[2]Monitor Audio Ltd., Rayleigh, Essex, United Kingdom

Loudspeaker simulation is used to inform the designer as to the performance of a design. In recent years the Finite Element Method (FEM) has been used to model the mechanical and acoustical attributes of a loudspeaker with varying success. This paper shows how a model that incorporates ... Mehr lesen

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 ... Mehr lesen
