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 ... En savoir plus

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 ... En savoir plus

A 2D Axisymmetric Electrodeposition Model

R. Pryor
Pryor Knowledge Systems, Inc.
Bloomfield Hills, MI

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 ... En savoir plus

3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets

M. Ainslie[1], J. Zou[1], D. Hu[1], D. Cardwell[1]
[1]Department of Engineering, University of Cambridge, Cambridge, UK

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... En savoir plus

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 ... En savoir plus

Highest Pulsed Magnetic Fields in Science and Technology, Assisted by Advanced Finite-Element Simulation

Thomas Herrmannsdörfer

Dr.
Forschungszentrum Dresden-Rossendorf, Germany

Thomas Herrmannsdörfer got his PhD in experimental physics from the University of Bayreuth in 1994. In 1995, he received the Research Award of the Emil-Warburg-Foundation while he worked at the DFG-Graduiertenkolleg Bayreuth. From 1995 – 1998 he worked as a scientist at Hahn-Meitner ...

Particle Flow Control by Magnetically Induced Dynamics of Particle Interactions

F. Wittbracht[1], A. Weddemann[1], A. Auge[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... En savoir plus

Parametric Model Of An Air-Core Measuring Transformer

D. Herceg
Faculty of Technical Science, Novi Sad, Serbia

Power grid voltages and currents may be distorted due to presence of harmonics. Measurements of such voltage with harmonics may be performed using newly developed instrument with a small air-core transformer based probe as the input unit. The probe must be shielded against unknown ... En savoir plus

Modeling of Microwave Heating of a Rotating Object in a Domestic Oven in COMSOL Multiphysics

J. Raj[1], S. Birla[2], K. Pitchai[3], J. Subbiah[2], and D. Jones[2]
[1]Indian Institute of Crop Processing Technology, Thanjavur, Tamil Nadu, India
[2]Dept. of Biological Systems Engineering, University of Nebraska Lincoln, Lincoln, NE
[3]Dept. of Food-Science, University of Nebraska Lincoln, Lincoln, NE

Domestic microwave ovens are notorious for their uneven heating of food materials. This is caused by a varying electromagnetic field whose variation is caused by a number of factors dependent on the oven and the food parameters. Experimental validation of heating would therefore give ... En savoir plus

Modelling of a Differential Sensor in Eddy Current Non-destructive Evaluation

A. Rosell[1], and G. Persson[2]
[1]Volvo Aero Corporation, Trollhättan, Sweden
[2]Chalmers University of Technology, Göteborg, Sweden

Interaction between the probe and a defect in eddy current non-destructive evaluation is studied. Evaluation of sensor signal response is the basis for the calculation. In this work a differential sensor is considered and the problem regarded here is problem 8 from the testing of ... En savoir plus
