Simulation of Field Enhancement in Anisotropic Transition Metamaterials using COMSOL

A. Pandey, and N. Litchinitser
The State University of New York at Buffalo
Buffalo, NY

Transition metamaterials constitute a new class of engineered materials which have material properties tailored in such a manner that the refractive index gradually changes from positive to negative. An important question is what happens at the interface of a positive and negative index ... En savoir plus

3D-model of an AC/DC Hybrid EHV Transmission Line to Analyze the Electrical Field along Insulators

D. Potkrajac [1], S. Papenheim [1], M. Kizilcay [1]
[1] University of Siegen, Siegen, Germany

To increase the power transfer capacity of existing lines, a transmission system operator in Germany plans to replace an existing 380-kV three-phase AC system into a bipolar HVDC system on the same tower that is called a 'hybrid line'. Due to the proximity of AC transmission systems and ... En savoir plus

Deep Learning Enabled Nanophotonic Design via Finite Element Simulation

A. Mall[1], A. Sethi[2], A. Kumar[1]
[1]Indian Institute of Technology Bombay, India
[2]Indian Institute of Technology, Bombay, India

Metamaterials and metasurfaces are emerging technologies in the field of nanophotonics. They can enable the engineering of arbitrary optical response based on their nano structure. The desired effective optical response is quantified by amplitude and phase of the light reflected and ... En savoir plus

AC/DC Modelling of Eddy Currents in Graphite Bricks at UK AGRs

R. Newson[1], C. Watson[1], M. Pogson[1]
[1]Quintessa, United Kingdom

EDF Energy use an Eddy Current Inspection Tool (ECIT) to test the properties of graphite bricks in the cores of UK Advanced Gas-cooled Reactors (AGRs). The tool comprises a coil containing an alternating current which generates a magnetic field, inducing eddy currents within the nearby ... En savoir plus

Validation of the Analytical Approximation for Induction Heating Ionic Solutions Using COMSOL Multiphysics®

M. Taylor[1]
[1]Perpetual Research Consultancy Ltd, United Kingdom

New methods of generating high-frequency magnetic fields of tens or even hundreds of millitesla at frequencies exceeding 2 MHz are allowing important new applications for induction heating. These include heating low conductivity ionic solutions in situations where electric or ... En savoir plus

Simulation of Sidewall Scattering Losses for Light Pipes

C. Madsen¹
¹Texas A&M University, College Station, TX, USA

The impact of surface roughness on the optical transmission of light pipes has been addressed using a geometric optics approximation (GOA); however, there has not been a comparison between the GOA and a wave optics solution to evaluate the relative impact of diffraction effects on the ...

Assessing Reliability of Embedded Resistor Designs in Integrated Circuit

R. Wulandana[1], P. Wang[1], L. McCary[1], S. Alzeq[1]
[1]State University of New York (SUNY) at New Paltz, USA

Localized Joule heating within integrated circuit (IC) chips is the leading cause of non-uniform temperature distribution within the circuit structure of the chips. Such variation in temperature enhances the biased diffusion of metal atoms along current carrying interconnects, a ... En savoir plus

3D Modeling of All-Superconducting Synchronous Electric Machine by Finite Element Method

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

This paper presents the electromagnetic analysis of an all-superconducting synchronous electric machine, focusing on AC loss calculations in high temperature superconducting (HTS) coils. The numerical analyses of two 3D models are shown, including the model of the machine and its HTS ... En savoir plus

CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates

G. Ruocco[1], M. V. De Bonis[2]
[1]Engineering College, University of Basilicata, Potenza, Italy
[2]Institute of Food Science and Production, National Research Council, Bari, Italy

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... En savoir plus

Pulsed Power Accelerator Design with COMSOL Multiphysics® Software

D. Reisman[1]
[1]Sandia National Laboratories, Albuquerque, NM, USA

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good ... En savoir plus
