Thermoelastic Model for Microwave Ablation of Concrete

B. Lepers[1], S. Soldatov[1]
[1]Karlsruhe Institute of Technology, Institute for Pulsed Power and Microwave Technology, Karlsruhe, Germany

The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

Inverse-Design in Large Photonic Gratings Enabling Efficient Photonic-to-Free-Space Mode Coupling

A. Yulaev¹, D. A. Westly², Vladimir A. Aksyuk²
¹Department of Chemistry and Biochemistry, University of Maryland, College Park, MD, USA
²PML, National Institute of Standards and Technology, Gaithersburg, MD, USA

Realization of an efficient coupling between photonic sub-micrometer size modes and hundred micrometer wide free-space beams remains a main engineering hurdle to a wider acceptance of miniaturized chip-scale atomic and bio systems. The major obstacle comes from a gigantic mode mismatch ... En savoir plus

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also ... En savoir plus

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 ...

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
