Virtual Homogeneous Isotropic and Real Unhomogeneous Anisotropic Metamaterials

Akalin, T.
IEMN (Institut d’Electronique de Microélectronique et de Nanotechnologie), CNRS UMR 8520, Dpt DHS, USTL (Université des Sciences et Technologies de Lille)

Characteristics on metamaterials and potential applications are presented with the FEMLAB® software simulations results. By definition, metamaterials are materials which exhibit properties which do not exist naturally. Another point is that metamaterials are associated with the negative refractive index property. In the first part, negative refraction will be defined and illustrated by ...

Skeletal Reduction of Boundary Value Problems over Thin Solids

Suresh, K.
University of Wisconsin – Madison

Boundary value problems posed over thin solids are amenable to a dimensional reduction in that one or more spatial variables may be eliminated from the governing equation, resulting in significant computational gains with minimal loss in accuracy. Extant dimensional reduction techniques unfortunately rely on representing the solid as a hypothetical mid-surface plus a possibly varying thickness. ...

Thermo-mechanical Behavior of Multilayers

Bilotsky, Y., Gasik, M.
Laboratory of Materials Processing and Powder Metallurgy, HUT, Finland

The model for study of thermal mechanical behavior of multilayer thin films was developed. The stress-strain analysis was carried out in combination with thermal effects. The 2D thinfilm model has been solved by FEMLAB 3.1i. The middle layer was thermally loaded with Ohmic heating and other layer’s thicknesses were varied in time. All material data like elastic coefficients, thermal ...

Electromagnetic simulations of Goubau transmission lines with FEMLAB

Akalin, T.
IEMN, Institut d’Electronique, de Microélectronique et de Nanotechnologie, UMR CNRS 8520, USTL Université des Sciences et Technologies de Lille, Villeneuve d’Ascq, France

The BioMEMS (Bio-Electro-Mechanical Systems) have become of considerable interest because they constitute a converging solution for many pluridisciplinary studies. The different covered fields are the biology (single cell, proteins, enzymes, neurons…), the chemistry (polymers), microelectronics and the microtechnologies associated with. Devices whose aim is the study of biological entities are ...

Modelling of continuous steel coating by self-induced ion plating

Contino, A.1, Feldheim, V.1, Lybaert, P.1, Deweer, B,2, Cornil, H.2
1 Faculty of Engineering – Thermal Engng. & combustion Lab., Mons – Belgium
2 Arcelor Innovation, Liège, Belgium

The self-induced ion plating (SIIP) process is a new physical vapor deposition process based on the evaporation of a metallic target (i.e. tin) thanks to a magnetron sputtering system. The aim of this work is to develop a numerical simulation model of the SIIP process in order to predict the target temperature field and from it, the coating profile on the substrate. The simulation of the SIIP ...

Simulation der elektrischen Feldverteilungen im elektrischen Rasterkraftmikroskop

Inertia Mixer in CD Microfluidics

G. Kylberg

Gyros AB is developing biomedical laboratories in CD-discs, Gyrolab®. In a lot of applications mixers are needed and for some special applications liquid volumes of a few microlitres are to be handled. The mixing of a few microlitres liquids was studied numerically with FEMLAB and experimentally with colored and uncolored water. Thanks to this combination, the main mixing process was ...

Finite Element Modeling a Redox-Enzyme-Based Electrochemical Biosensor

Y. Huang[1], and A. Mason[1]
[1]Electrical and Computer Engineering, Michigan State University, East Lansing, Michigan, USA

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak current. The biosensor is constructed by immobilizing redox-enzyme on an interdigitated array (IDA) electrode ...

Oil Discharge and Transport in a Natural River

Tomas Ekström1,Klara Linden2
1Carl Bro AB Energy, 2Lunds University

A discharge of hydraulic oil is assumed from an hydroelectric power station. The oil is let out through the outlet from the turbines and is spread into the river. The flow of water, or more correctly, the solution of water and oil, is calculated by Navier-Stoke equation for incompressible fluids. The concentration of oil is calculated by a mass-balance equation. It is assumed that oil is absorbed ...
