Simulation of the Dynamic Behavior of a Droplet on a Structured Surface using the Non-conservative Level Set Method

N. Boufercha, J. Sägebarth, and H. Sandmaier
Universität Stuttgart / IFF-MST, Stuttgart, Germany

The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by ... Read More

DNA Interactions in Crowded Nanopores

K. Misiunas[1], N. Laohakunakorn[1], S. Ghosal[2], O. Otto[1], U. F. Keyser[1]
[1]University of Cambridge, Cambridge, UK
[2]Northwestern University, Evanston, IL, USA

The motion of DNA in crowded environments is a common theme in physics and biology. Examples include gel electrophoresis and the self-interaction of DNA within cells and viral capsids. Here we study the interaction of multiple DNA molecules within a nanopore by tethering the DNA to a ... Read More

Simulation on antireflection of the oxide nanosphere monolayer film

李晓红 [1], YUXIAO HOU, HANG LUO, WEI LEI, HONG LEI [1],
[1] 西南科技大学

We theoretically simulate the antireflective effects of oxide nanosphere monolayer films in the visible spectrum. The essential geometric and material parameters of nanosphere films are simulated and different functions are proposed to describe the dependence of reflectance on the ... Read More

Non-Equilibrium Quantum Well Populations and Optical Characteristics of III-Nitride Lasers and Light-Emitting Diodes

M. Kisin, and H. El-Ghoroury
Ostendo Technologies, Inc.
Carlsbad, CA

COMSOL-based Ostendo’s Optoelectronic Device Modeling Software (ODMS) has been updated to include effects of non-equilibrium QW populations in semiconductor light-emitting and laser diodes. III-nitride light emitters with different levels of polarity have been compared as an ... Read More

Modeling of Random Nanostructures Based on SEM Images and Analysis of Resulting RF-Performance

K. Neumann [1], J. Moeller [1], L. Kuehnel [2], A. Rennings [1], N. Benson [2], R. Schmechel [2], D. Erni [1],
[1] General and Theoretical Electrical Engineering (ATE), University of Duisburg-Essen, and CENIDE – Center for Nanointegration Duisburg-Essen, Duisburg, Germany
[2] Institute for Nanostructures and Technology (NST), University of Duisburg-Essen, and CENIDE – Center for Nanointegration Duisburg-Essen, Duisburg, Germany

In the last few years printable electronics has gained a great deal of interest since it promises mechanical flexibility and extremely low production costs. One approach to achieve printable electronic devices relies on the usage of specific inks containing e.g. dispersed semiconductor ... Read More

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. ... Read More

3D Thermo-Acoustic Modeling of a Piezo Transducer for Directed Interstitial Ultrasound Ablation

K. Y. Gandomi¹, Z. Zhao¹, P. A. Carvalho¹, C. J. Nycz¹, G. S. Fischer¹, E. C. Burdette²
¹Worcester Polytechnic Institute, Worcester, MA
²Acoustic Medsystems Inc., Savoy, IL, USA

Thermal ablation is a treatment option in oncology that can be used to target primary and metastatic cancers. In this approach, high temperature heating is administered at the target tumor site to induce coagulative necrosis of malignant cells. One minimally invasive method for ... Read More

Numerical Modelling and Validation of Induction Melting of IN713C for Investment Casting

V U Thomas¹, M A Yar¹, S Mehraban¹, J C T Cullen¹, S G R Brown¹, N P Lavery¹
¹Swansea University, UK

Investment casting is practised in both the automotive and aerospace industries, to produce casted components where a high-quality surface finish is critical. Vacuum induction melting (VIM) and direct pouring into an investment casting shell mould is an advantageous manufacturing ... Read More

Study of the Optical Field Scattering Enhancement on a 2D Rough Surface Using COMSOL Multiphysics®

P. de Carvalho Gomes [1], P. Goldberg Oppenheimer [1]
[1]School of Chemical Engineering, University of Birmingham, UK

Surface Enhanced Raman Scattering (SERS) phenomenon is well known for its detection sensitivity, however, to better understand how it works a better insight needs to be developed on the physics behind the phenomenon. The physical aspects known to produce SERS effect are the use of ... Read More
