Finite Element Modeling of a Microwave Cavity under Resonant Conditions

T. W. Krause [1], F. Liu [1], S. Gauvin [2],
[1] Department of Physics and Space Science, Royal Military College, Kingston, ON, Canada
[2] Department of Physics, Engineering Physics and Astronomy, Queens University, Kingston, ON, Canada

A tapered cylindrical microwave resonant cavity, a frustum, also commonly known as an EM Drive, has been reported to produce thrust by the generation of EM radiation within a resonant cavity without using any propellants. In order to determine how a sealed microwave cavity can produce ... Read More

Modeling the Interaction of Light with Plasmonic Nanoparticles

T. Gál[1], Ö. Sepsi[1], P. Koppa[1]
[1]Budapest University of Technology and Economics, Budapest, Hungary

Plasmonic nanoparticles have received increased interest due to their numerous potential applications in the field of optics and optoelectronics. Currently such metallic nanoparticles are applied in semiconductor devices, such as light emitting diodes (LEDs) and solar cells. The optical ... Read More

Simulating the Response of Planar Photonic Structures Under the Strain of Surface Acoustic Waves

O. D. D. Couto Jr. [1], A. C. T. Covacevice [1],
[1] Instituto de Física Gleb Wataghin, Universidade Estadual de Campinas, Campinas, SP, Brazil

In this contribution, we simulate the optical response of piezoelectric planar optical microcavities (POMCs) under the modulation introduced by a propagating surface acoustic wave (SAW). The physical picture of the model is shown in Figure 1. A metallic interdigital transducer (IDT) is ... Read More

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 ... Read More

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 ... Read More

Computer Simulation of Microwave Heating of Initially Frozen Sandwiches Using COMSOL Multiphysics® Application Builder

D. Fu [1], L. Wang [2], J. Liao [1], S. Dus [1], K. Bearson [1],
[1] Tyson Foods, Downers Grove, IL, USA
[2] Simulprocess, Summerfield, NC, USA

Customers typically prepare sandwiches using a microwave oven to heat a frozen sandwich. This causes huge temperature variations and quality issues due to multicomponent with different dielectric and physical properties and with phase changes at different freezing points in the heating ...

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 ... Read More

A triple band cross-polarization converter based on ultra-thin graphene-integrated metasurface

Zhifei Yao [1], Yueke Wang [1], Shumei Gao [1],
[1] Optical Information Science and Technology Department, Jiangnan University, Wuxi, Jiangsu, china

We propose a triple band tunable and high-efficient reflected cross-polarization converter (CPC) in the mid-infrared. The study of graphene-integrated CPC becomes increasingly important, due to its tunable optical performance and small volume. Graphene, a monolayer of carbon atoms ... Read More

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 ... Read More

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 ... Read More
