In a first approach towards application of the magnetic frequency mixing technique to microfluidic structures, microplanar coils have to be designed along with sample reservoir. For this, a COMSOL Multiphysics® electrical model along with an analytical calculation is used in order to ... En savoir plus

Theoretical Study Of Porous Silicon Waveguides And Their Applicability For Vapour Sensing

T. Hutter[1], N. Bamiedakis[2], and S. Elliott[1]
[1]Department of Chemistry, University of Cambridge, UK
[2]Centre for Advanced Photonics and Electronics, Engineering Department, University of Cambridge, UK

The finite-element method (FEM) (COMSOL RF Module) has been employed for modal analyses of porous silicon (PSi) waveguides composed of a guiding layer of low porosity (high refractive index) on a cladding layer with higher porosity (lower refractive index). These can be made by switching ... En savoir plus

Chaotic Behavior of the Airflow in a Ventilated Room

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been ... En savoir plus
