Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating ... Mehr lesen

Thermal and Solid-Mechanics FEM Simulation of a Microwave Spatial Power Combiner Amplifier

A. Leggieri[1], F. Di Paolo[1], D. Passi[1]
[1]University of Rome "Tor Vergata" - Department of Electronic Engineering, Rome, Italy

This paper describes the thermal and structural combined simulation on COMSOL Multiphysics® of a Microwave (MW) Fin Taper (FT) Spatial Power Combiner (SPC) Power Amplifier (PA), based on rectangular Waveguide (WG). In the SPC based PA's, the captured power is feeded by microstrip ... Mehr lesen

Microwave Radiation to Cure Cork Stoppers Using a Conventional Turntable Configuration

D. Fidalgo[1], J. Monteiro[1], L. Costa[1]
[1]I3N and Physics Department, University of Aveiro, Aveiro, Portugal

This work presents an alternative method for curing cork stoppers based on microwave radiation, which is energetically more efficient, where it is possible to accelerate the reaction rate and therefore reduce the cure time comparatively with conventional curing methods. The microwave ... Mehr lesen

Inverse Model for Solving Partial Differential Equations Using a Stochastic Method and COMSOL Multiphysics®

E. Khosrowshahli[1], A. Jeremic[1]
[1]McMaster University, Hamilton, ON, Canada

Partial differential equations (PDEs) govern many phenomena in nature. Solving optimization problems which comprises the solution of large number of PDEs, is expensive concerning time and memory. Therefore, to reduce the solution cost, original problem is transformed to a corresponding ... Mehr lesen

Electrical Response and Thermal Damage Assessment of Cutaneous and Subcutaneous Tissues to Noninvasive Radiofrequency Heating: A Computational Modeling Study

[2]Biomedical Synergy, Electronic Engineering Department, Universitat Politècnica de València, Valencia, Spain
[3]ZELTIQ Aesthetics, Inc., Pleasanton, CA, USA

Electromagnetic radiofrequency (RF) sources are widely used to heat up cutaneous and subcutaneous tissues. The subcutaneous morphology of tissue consists of a fine, collagenous and fibrous septa network enveloping clusters of adipocyte cells; however, it is commonly regarded as a ... Mehr lesen

Pros and Cons of Running COMSOL Multiphysics® Touch-Sensor Simulations on Amazon Web Services™

A. Gourevitch[1]
[1]Cypress Semiconductor Corp., San Jose, CA, USA

We report an implementation of parallel computing on Amazon Web Services™ (AWS) for touch-sensor modeling. COMSOL Multiphysics® was used to simulate an electromagnetic field distribution in a capacitive sensor assembly. Multiple COMSOL jobs were deployed on separate AWS instances and ... 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

Calculation of Capacitances of Symmetrical Triple Coupled CPW Transmission Lines and Multilayer CPW Broadside Coupled Lines Balun

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of symmetrical triple coupled ... Mehr lesen

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 ... Mehr lesen
