Demonstration of Polymer Microring Resonator for Optical Biosensor using COMSOL

Mohd Haziq M.S.[1]
Mohd Hazimimin Mohd Salleh[2]

[1]Department of Information Systems, Kulliyyah of Information and Communication Technology, International Islamic University Malaysia, Kuala Lumpur, Malaysia

[2]Department of Physics, Kulliyyah of Science, International Islamic University Malaysia, Pahang, Malaysia

In this paper, we use a COMSOL Multiphysics® model to demonstrate the potential use of polymer microring resonator structures for optical biosensing applications. When the refractive index of the area surrounding the microring resonator changes, there is a shift in the resonance ... Read More

Optoelectronic Simulation of An Organic Bulk Heterojunction Solar Cell with COMSOL

Koh Wee Sing[1]
[1]Institute of High Performance Computing, Agency for Science, Technology, and Research, Singapore, Singapore

In this project, we developed a 3D optoelectronic model for organic bulk-heterojunction solar cells. We validated our COMSOL Multiphysics® model with experimental data and used our simulation to predict the optical and electrical characteristics of a 3D plasmonic OPV device. This work ... Read More

Numerical and Experimental Study of Water Drop Movement Subjected to an Air Stream in Porous Medium

A. Yekta[1], D. Stemmelen[1], S. Leclerc[1]
[1]LEMTA,UMR 7563 CNRS - Université de Lorraine, 54518 VANDOEUVRE-LES-NANCY France

Considering a liquid drop in relative movement with respect to the air flow at uniform velocity, the liquid will be driven to the surface by the viscous friction. Internal vortices will appear inside the drop. This problem has already been studied in fluid mechanics and is well known as ... Read More

Dielectrophoresis (or DEP) has been exploited for various micro and nano fluidics applications like patterning, sorting and separation. However, there are several commonly neglected issues in quantifying DEP forces. Such negligence could potentially lead to wrong DEP force predictions ... Read More

Actively Controlled Ionic Current Gating In Nanopores

G. Zhang[1], S. Bearden[1]
[1]Clemson University, Clemson, SC, USA

It is necessary to understand and control nanopore behavior in order to develop biosensors for a variety of applications including DNA sequencing. The fluidics of nanopore devices we fabricated exhibits a range of interesting phenomena, such as enhanced conductance and current ... Read More

Analysis of Working Fluid Flow and Debris Behavior in Micro-EDM Gap Area

Masashi MACHIDA[1]

[1]Tokyo University of Agriculture and Technology, Fuchu, Tokyo, Japan

Debris, micro particles produced by discharges, stay in the gap area during deep hole machining by micro EDM, cause short-circuits and abnormal discharges, finally make machining impossible. Although a deep hole can be processed by using the tool with grooves on the surface, the effect ... Read More

Vibration Analysis of the Wineglass for Glass Harp using COMSOL Multiphysics®

Teruyuki KOZUKA[1]

[1]National Institute of Advanced Industrial Science and Technology, Tokyo, Japan

When a wineglass is touched with a wet finger along its edge, it vibrates at single frequency and you hear a clear sound. If the water is added into the glass, the sound pitch changes because the resonance frequency changes with the mass of the glass. When there are plural glasses with ... Read More

Numerical Model for Leaching and Transporting Behavior of Radiocesium in MSW Landfill

Hiroyuki ISHIMORI et al.[1]

[1]Ritsumeikan University, Kyoto, Kyoto, Japan

This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for ...

Temperature Measurements of a Single Gold Nanoparticle under Laser Illumination

Kenji SETOURA et al.[1]

[1]The University of Tokushima, Tokushima, Tokushima, Japan

Temperature measurement of nanoparticles (NPs) under heating is an important technique in order to achieve potential applications such as photothermal cancer therapy and nanofabrication. We implemented the method to estimate the local temperature of a laser-heated gold NP on glass ... Read More

AC Loss Computation of Single Isolated Superconducting Tapes

Batdalai SUKH et al.[1]

[1]Miyakonojo National College of Technology, Miyakonojo, Miyazaki, Japan

In this panel session we present numerical models for computing the current density, field distribution and AC losses in high-temperature superconducting tapes. The tapes have a rectangle cross section for two-dimensional geometries. The numerical models are tested by comparing the ... Read More
