COMSOL Multiphysics® Investigation of Radiative and Nonradiative Channels of Quantum Emitter Fluorescence near Hyperbolic Metamaterial

A. Pavlov[1], V. Klimov[1], I. Zabkov[2], D. Guzatov[3]
[1]Lebedev Physical Institute, Moscow, Russia
[2]Moscow Institute of Physics and Technology, Dolgoprudnj, Russia
[3]State University of Grodno, Grodno, Belarus

Effective control over single atom emission might lead to major breakthrough in the field of nanotechnology. It is believed that use of hyperbolic metamaterials (HMM) can be helpful. COMSOL Multiphysics® was used to model interaction of electric dipole with effective HMM and calculate ... Per saperne di più

A Computational Approach for Simulating p-Type Silicon Piezoresistor Using Four Point Bending Setup

T.H. Tan[1], S.J.N. Mitchell[1], D.W. McNeill[1], H. Wadsworth[2], S. Strahan[2]
[1]Queen's University Belfast, Belfast, United Kingdom
[2]Schrader Electronics Ltd, Antrim, United Kingdom

The piezoresistance effect is defined as change in resistance due to applied stress. Silicon has a relatively large piezoresistance effect which has been known since 1954. A four point bending setup is proposed and designed to analyze the piezoresistance effect in p-type silicon. This ... Per saperne di più

Incoherent Propagation of Light in Coherent Models

A. Čampa[1], J. Krč[1], M. Topič[1]
[1]University of Ljubljana, Faculty of Electrical Engineering, Ljubljana, Slovenia

In the finite element based modeling and simulations only the coherent propagation of light is considered. However, in reality when light passes the thick layer it loses the phase information and its coherent nature due to the spatial, temporal or spectral incoherence. In this work, we ...

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 ...

Simulation, Fabrication and Observation of Plasmonic Halos

F. Ye[1], M. Burns[1], J. Merlo[1], M. Naughton[1]
[1]Department of Physics, Boston College, Chestnut Hill, MA, USA

We present the simulation, observation and systematic study of a novel optical phenomenon, a “plasmonic halo”, wherein optically pumped surface plasmons on circular silver microcavities form confined drumhead modes that, under off-resonant conditions, transform to colorful far field ...

Mie Scattering of Electromagnetic Waves

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

The Mie solution to the scattering of electromagnetic waves by spherical particles has been examined using COMSOL Multiphysics®. The results assume elastic scattering only and do not include Brillouin or Raman scattering. The nature of the interaction has been considered for materials ... Per saperne di più

Calculation of Capacitances of Symmetrical Triple Coupled CPW Transmission Lines and Multilayer CPW Broadside Coupled Lines Balun

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of symmetrical triple coupled ... Per saperne di più

Modeling Light Propagation in Skin for Visualization of Subcutaneous Veins

H. Kwon[1], R. Huancaya[1]
[1]Andrews University, Berrien Springs, MI, USA

Vein visualization systems such as the VeinViewer are vein-contrast enhancement devices that use an infrared camera to highlight blood or the underlying vasculature and project the image in real time onto the skin. Understanding the light propagation in a realistic skin model is ... Per saperne di più

Designing and Simulating THz Guided Wave Devices Using Finite Element Techniques

L. M. Hayden[1], D. A. Sweigart[1]
[1]Department of Physics, University of Maryland Baltimore County, Baltimore, MD, USA

The generation of terahertz frequency radiation (0.1-10 THz) is an important technological goal due to the use of this non-ionizing radiation to penetrate a wide range of non-conducting materials. One outstanding problem has been the propagation of THz radiation in guided wave devices. ... Per saperne di più
