Analysis of Geometrical Aspects of a Kelvin Probe

I. Kuehne [1], S. Ciba [1], A. Frey [2],
[1] Heilbronn University, Kuenzelsau, Germany
[2] University of Applied Sciences, Augsburg, Germany

The presented analysis investigates the capacitance characteristic of a Kelvin probe regarding the geometrical transition from a movable electrode plate to a narrow tip. Moreover, predictions can be done concerning optimum geometry, sensitivity and suitable electrical measurement ... En savoir plus

Magnetoacoustic Tomography and COMSOL Multiphysics

W. He
Chinese Academy of Sciences, Institute of Electrical Engineering, Beijing, China

Magnetoacoustic tomography with magnetic induction (MAT-MI) is a recently introduced method for imaging electrical impedance properties, which integrates classic electrical impedance tomography and ultrasonic technique. It could provide an explicitly reconstructed electrical impedance ... En savoir plus

Effect of Manufacturing Defects in the Form of Internal Leakages on the Acoustic Performance of Mufflers

D. Neihguk[1], A. Prasad [1]
[1] Mahindra & Mahindra Ltd, Chengalpattu, Tamil Nadu, India

The presence of manufacturing defects in the form of incomplete welding and missing perforated holes leads to internal leakages in mufflers. This results into unintended acoustic impedance modifications as well as the Herschel-Quincke effect. The narrow region acoustics model of COMSOL ... En savoir plus

Design and Optimization of Circularly Polarized Antennas for Mobile Shooting of Sport Events

A. De Vita[1], B. Sacco[1], A. Lucco Castello[1]
[1]RAI - Radiotelevisione italiana, Italy

IntroductionA new circular polarized antenna model for mobile transmission has been implemented in COMSOL Multiphysics® for needs related to shooting sports events on the move. The antenna was required to work in the UHF television frequency band (specifically, 600 MHz) and, if ... En savoir plus

A Simulation Test Bench for Decay Times in Room Acoustics

R. Magalotti [1], V. Cardinali [1],
[1] B&C Speakers S.p.A., Bagno a Ripoli (FI), Italy

An important yet rarely explored problem in room acoustics is how to correlate the decay times of modal resonances to the acoustic properties of the boundaries (walls). The room response is often described by reverberation times, but the reverberation model breaks down at low frequency, ... En savoir plus

Simulation of the Electrical Properties of Conductive ITO Thin Films by Finite Element Analysis

R. A. Gerhardt [1], N. Xia [1], Y. Jin [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Finite element analysis (FEA) can be used to study the electrical properties of conductive ITO thin films. Previous studies have been done on insulating thin films deposited on conductive substrates [1,2]. It was found that changes of electrode size and film thicknesses can cause huge ... En savoir plus

Electromagnetic Modeling of a Millimeter-Wavelength Resonant Cavity

J. C. Weatherall [1], J. Barber [1], B. T. Smith [2], J. Greca [1],
[1] Battelle Memorial Institute, Norwell, MA, USA
[2] U.S. Department of Homeland Security, Science and Technology Directorate, Washington, DC, USA

The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency ... En savoir plus

Simulation of Eddy Current Non Destructive Testing using COMSOL Multiphysics®

A. Kyrgiazoglou [1], T. Theodoulidis [1],
[1] Department of Mechanical Engineering, University of Western Macedonia, Kozani, Greece

Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... En savoir plus

Development of a Microfluidic-Based Electrochemical Cell for Analyzing Bacterial Biofilms

I. Claydon [1], J. Turner [1], B. Sammakia [1],
[1] Binghamton University, Binghamton, NY, USA

The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of ... En savoir plus
