Plasmon Enhanced Fluorescence Characteristics Government by Selecting the Right Objective Function

M. Csete [1], A. Szenes [1], D. Vass [1], B. Bánhelyi [2], T. Csendes [2], G. Szabó [1]
[1] Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary
[2] Department of Computational Optimization, University of Szeged, Szeged, Hungary

Core-shell type plasmonic nanoresonators have been optimized to maximize the fluorescence rate of coupled dipolar emitters, namely SiV color centers in diamond. The RF module of the COMSOL Multiphysics® software was applied to extract the optical response and to analyze the near-field ... Read More

Decomposition of Fundamental Lamb Wave Modes in Complex Metal Structures Using COMSOL Multiphysics®

M. Harb [1], R. Malaeb [1], E. Mahfoud [1],
[1] Department of Mechanical Engineering, American University of Beirut, Libanon

Structural Health Monitoring Systems are being highly investigated to evaluate the health of a structure and detect any damages occurring in real time. Such systems require intensive data analysis which gets even more intricate when working with complex structures due to undesirable ... Read More

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Read More

Magnetic Ratchet

A. Auge, F. Wittbracht, A. Weddemann, and A. Hütten
Department of Physics, University of Bielefeld, Germany

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux ... Read More

Photoacoustic Modeling Using Amplitude Mode Expansion Method in a Multi-Scale T-cell Resonator

S. El-Busaidy [1], B. Baumann [1], M. Wolff [1], L. Duggen [2],
[1] Hamburg University of Applied Sciences, Germany
[2] University of Southern Denmark, Denmark

The photoacoustic (PA) effect consisting of the generation of an acoustic signal based on the absorption of light has already demonstrated its potential for various spectroscopic applications for both gaseous and solid samples. The signal produced during photoacoustic spectroscopy (PAS) ... Read More

An App for Additive Manufacturing Design Assessment

B. Lazaro Toralles [1], S. Afazov [1], A. Yaghi [1], W. A. D. Denmark [1], A.N. Holloway [1],
[1] The Manufacturing Technology Centre Ltd., Coventry, United Kingdom

The Manufacturing Technology Centre (MTC) is home to the UK’s National Centre for Net Shape and Additive Manufacturing, offering integrated solutions to potential end users, supply chain companies or equipment providers using a three phase approach: discovery, demonstration and pilot ... Read More

Modelling of the Hydrogen Diffusion in Martensitic Steel in Contact with H₂SO₄ Media

J. Bouhattate[1], X. Feaugas[1], and S. Frappart[1][2]
[1]Laboratoire d’Etudes des Matériaux en Milieux Agressifs,
Université de La Rochelle, La Rochelle, France
[2]V&M France, CEV, Aulnoye-Aymeries, France

Hydrogen Embrittlement (HE) is one of the mechanisms responsible for premature failure of structures. In the context of environmental sustainability, it is compelling to improve or conceive new processes and/or new materials capable of reducing fracture induced by HE. We analyzed the ... Read More

Modeling the Thermally Induced Curvature of Multilayer Coatings with COMSOL Multiphysics^TM

H. Conrad[1], T. Klose[2], T. Sandner[2], D. Jung[1], H. Schenk[2], and H. Lakner[1,2]
[1]Semiconductor and Microsystems Technology Laboratory, Technische Universität Dresden, Germany
[2]Fraunhofer Institute for Photonic Microsystems Dresden, Germany

Within this paper the so called “birth and death” method is demonstrated in use with COMSOL Multiphysics®. With this method the free and reactionless movement of a solid structure on deformed geometries and the activation of this solid structure at later simulation steps is possible. For ... Read More

Modelling of Lintel-Masonry Interaction Using COMSOL

A. Vermeltfoort, and A. van Schijndel
Eindhoven University of Technology, Netherlands

An attempt was made, as described in this paper, to assign material properties like shear strength and modulus of elasticity randomly. In this way, the behaviour of a masonry wall with a prefabricated concrete lintel was experimentally tested and simulated using COMSOL. The paper ... Read More

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J.-D. Wheeler [1], ,
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... Read More
