The investigation focuses on the separation phenomena and the manifestations of vortical structures in a Y-bifurcation with a square cross-section. A micro-PIV measurement system is used to obtain velocity profiles distributions in the primary flow domain and in the secondary ones (vortex zones). The experimental data is compared to numerical simulations performed with FLUENT™ code in 3D geometries. Calculated flow patterns are found to be consistent with experiment manifestations, offering useful insights on the vortical structures in the analysed applications.","PeriodicalId":9628,"journal":{"name":"CAS 2012 (International Semiconductor Conference)","volume":"1 1","pages":"274-250"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77314253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A boundary integral equation (BIE) method has been used in the electrostatic approximation. The BIE method allows a transparent eigenmode decomposition of both the far-field and near-field, which are valid as long as the size of the nanoantenna is much smaller than every representative light wavelength. Our near-field calculations show that for a rod-like nanoantenna with a length below 100 nm the electrostatic and the fully retarded results are in good agreement with each other.","PeriodicalId":9628,"journal":{"name":"CAS 2012 (International Semiconductor Conference)","volume":"113 1","pages":"415-418"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79828673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we discuss a fundamental change of technological paradigm based on nanoprinting-techniques which implementation will successfully address all the bioNEMS-related issues at once. The choice of the nanoprinting-based techniques as a generic way to both fabricating (by transfer-printing) and functionalizing (by nano-contact printing) ultra-dense arrays of NEMS (thousands per cm2) could lead to easy-to implement, flexible recipes for front-end and back-end processing while avoiding a long series of technological steps which most of the times dramatically impacts the yield, and subsequently the cost of fabrication.","PeriodicalId":9628,"journal":{"name":"CAS 2012 (International Semiconductor Conference)","volume":"126 1","pages":"51-56"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81331825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
