Interaction between Light Wave and Asymmetric Metal/Insulator/Metal (MM) Structure Coupled with Subwavelength Holes at Optical Fiber Apex
Osaka University, Suita, Osaka, Japan
Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of asymmetric metal/insulator/metal (MIM) layers coupled with subwavelength holes. Behavior of surface plasmon ...
Dependence of the Current Density Distribution with Flow Channel Geometry in a Half-Cell Model - new
O. Beruski, J. Perez
Institute of Chemistry of São Carlos, São Carlos, SP, Brazil
The present work demonstrates that a simple half-cell model is capable of reproducing qualitatively the main features of the measurements of the current density distribution in a high-temperature polymer electrolyte fuel cell, pointing that computational modeling and simulation are an important tool in the development of such devices. Our main interests with such a model is to optimize working ...

The design of windows and or other perforated structures which allow the free flow of air into & out of a building or system, while being fully soundproofed or attenuate certain frequencies is of great interest to architects and design engineers, where sound as a longitudinal wave, is difficult to separate it from its medium of propagation. In this work, we present the analysis of air ...

The greatest challenge being faced for realization of Micro-Electro Mechanical System (MEMS) technology is the lack of a simple, quick and reliable method for the fabrication of 3-D microchannel in the range of micrometers. A novel fabrication technique which opens possibilities for the production of these microfluidic channels is presented in this paper. The present paper highlights the ...

The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost. However, the performance of such systems is still not competitive when compared to traditional electrodynamic loudspeakers. In order to achieve an appropriate performance, one option is to ...

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, reducing stress on power generation infrastructure. Batteries firm the output capacity of intermittent wind ...

The DUNE experiment (http://www.dunescience.org/) is an international collaboration of more than 100 research institutes and universities (among them CERN and Fermilab) which is taking the challenge of building the next-generation experiment for the study of neutrino particles. The detector conceived to detect neutrinos consists of a gigantic cryogenic apparatus able to keep 700,000 tons of ...

With the development of micro and nanotechnologies, integrated structures based on piezoelectric thin films are widely investigated and their characterization become a crucial issue for the development of new applications. A laser interferometry is here used to assess the mechanical response in quasistatic regime of a piezoelectric sample. To complete this experimental approach, a numerical ...
Influence of Non-Newtonian Blood Viscosity on Wall Pressure in Right Coronary Arteries with Serial Stenoses
B. Liu 
 Monmouth University, West Long Branch, NJ, USA
Three dimensional mathematical models are developed to simulate the blood flows in patient specific right coronary arteries with two stenoses. Simulations are carried out with various flow parameters under physiological conditions. Both Newtonian and non-Newtonian blood viscosity models are applied in the simulations to examine the influence of non-Newtonian viscosity of blood on the wall ...
