Optimized Illumination Directions of Single-Photon Detectors Integrated with Different Plasmonic Structures

M. Csete[1], Á. Sipos[1], A. Szalai[1], G. Szabó[1]
[1]Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary

The optimal orientations of different single-photon detector designs were determined by COMSOL software package. Absorption of niobium-nitride (NbN) stripes in two different (p=220 nm, 3p=660 nm) periodic patterns integrated with plasmonic elements was studied. In OC-SNSPDs consisting ... Read More

3-D Design, Electro-Thermal Simulation and Geometrical Optimization of Spiral Platinum Micro-Heaters for Low Power Gas Sensing Applications Using COMSOL 4.1

V. Bansal, D. Kumar, B. Prasad, and A. Gujjar
Electronic Science Department

In this paper a thermal electric finite element method (FEM) analysis was used to investigate the thermal properties of individual electrically driven platinum micro-heaters. The geometric optimization for the micro-heater was performed by simulating a wide range of possible geometries ... Read More

Surface Plasmon Resonance

J. Crompton[1], S. Yushanov[1], L.T. Gritter[1], K.C. Koppenhoefer[1]
[1]AltaSim Technologies, Columbus, OH, USA

The resonance conditions for surface plasmons are influenced by the type and amount of material on a surface. Full insight into surface plasmon resonance requires quantum mechanics considerations. However, it can be also described in terms of classical electromagnetic theory by ... Read More

Lamb Waves and Dispersion Curves in Plates and It’s Applications in NDE Experiences Using Comsol Multiphysics

P. Gómez, J. P. Fernandez, and P. D. García
Hydro-Geophysics & NDE Modeling Unit
University of Oviedo
Mieres, Spain

In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional ... Read More

[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada
[2]Department of Physics, Engineering Physics and Astronomy, Queen's University, Kingston, ON, Canada

Steam generator (SG) tubes in CANDU® nuclear reactors can lose efficiency in the presence of corrosion and its by-products. Condition monitoring of support structures could help direct maintenance activities and thereby increase SG tube lifetime. Pulsed eddy current (PEC) has been ... Read More

Optimization of the Herringbone Type Micromixer Using Numerical Modelling and Validation by Measurements

E. Tóth[1], K. Iván[1], P. Fürjes[2]
[1]Pázmány Péter Catholic University, Budapest, Hungary
[2]Research Centre for Natural Sciences Institute for Technical Physics and Materials Science Hungarian Academy of Sciences, Budapest, Hungary

COMSOL Multiphysics® software was used in this study to simulate mixing by diffusion and by secondary flow. Particle tracing model was applied to simulate the mixing of cells in the microchannel. Results agreed well with the measurement, an optimal herring-bone structure was proposed for ... Read More

Three-Dimensional Simulation of Signal Generation in Wide-Bandgap Semiconductor Radiation Detectors

J. E. Toney[1]
[1]Pennsylvania State University Electro-Optics Center, Freeport, Pennsylvania, USA

We demonstrate the use of Comsol Multiphysics with Matlab to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and ... Read More

Predicting the Retention Time of Nuclear Reaction Products in the PSI Recoil Chamber Using COMSOL Multiphysics

R. Dressler[1], R. Eichler[1]
[1]Paul Scherrer Institute, Villigen, Switzerland

Introduction: The chemical properties of the heaviest elements (atomic number Z > 103) depend on the influence of the high nuclear charge to their electronic structure. Enhanced chemical stability of copernicium (Cn, Z = 112) and flerovium (Fl, Z = 114) was predicted already 40 year ago ... Read More

Enhancement of Terahertz Emission by AuGe Nanopatterns
