COMSOL Multiphysics® Software as a Metasurfaces Design Tool for Plasmonic-Based Flat Lenses

B. Adomanis [1], D. B. Burckel [2], M. Marciniak [1],
[1] Air Force Institute of Technology, Wright-Patterson AFB, OH, USA
[2] Sandia National Laboratories, Albuquerque, NM, USA

Introduction: Flat lenses require precise control of a phase gradient across an interface, which is enabled through the application of engineered surfaces, such as Metasurfaces [1]. Periodic arrays of plasmonic antennas have been utilized to generate this desired phase gradient, which ... Read More

A 2D Model of a DC Plasma Torch

B. Chine' [1],
[1] School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica

Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the ... Read More

Prediction of the Loudspeaker Total Harmonics Distortion Using COMSOL Multiphysics® Software

F. Malbos [1], M. Bogdanski [2], M. Strauss [2],
[1] Harman, Paris, France
[2] Harman Becker Automotive Systems, Straubing, Germany

For automotive applications, simulation methods are used to get the best audio acoustic performance. Because a loudspeaker is a non linear device, the sound pressure in the vehicle includes harmonics which are mainly created by the force factor, suspension stiffness and voice coil ... Read More

Modeling Cracking in Quasi-Brittle Materials Using Isotropic Damage Mechanics

T. Gasch [1], A. Ansell [1],
[1] KTH Royal Institute of Technology, Stockholm, Sweden

An extension of the Solid Mechanics interface in COMSOL Multiphysics® is presented to analyze localized deformations of quasi-brittle materials, for example cracking in concrete. This is achieved by implementing an isotropic damage mechanics constitutive law, which is combined with both ... Read More

Optimization of a Thermoelectric Conversion System

J. R. Chase [1],
[1] Alphabet Energy, Hayward, CA, USA

Thermoelectric materials have no theoretical limit to conversion efficiency of heat into electrical power. In order to compete with other forms of power generation and small-scale energy conversion, thermoelectric converters need to maximize their practical usability when integrated with ... Read More

Calculation of Inductance of Sparsely Wound Toroidal Coils

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corporation, Hauppauge, NY, USA

Analytical methods used for inductance calculation of toroidal coils yield large errors in the case of coils sparsely wound on low permeability cores. Numerical field calculations can provide “exact” figures. We have outlined several simulation methods. Simplifications, assumptions, and ... Read More
