Surprisingly, no regulations are currently in force which cover the RF transparency of buildings. It may well be justifiable on health and safety grounds (i.e. use of mobile phones or TETRA radio in emergency situations). For instance, there is substantial use of metal within current buildings which causes major problems for radio propagation. On the other hand, Building Information Modelling (BIM) is seen as a key technology and methodology to improve productivity and integration across various disciplines throughout the Architecture, Engineering and Construction (AEC) value chain. Although many valuable information has been added to such databases in the last years, detailed information about the radio wave propagation characteristics of buildings and building materials have been absent. This paper presents a multilayer Electromagnetic (EM) simulation tool to assess the radiofrequency transparency of building wall structures, which allows to explore different layer arrangements and determine the overall frequency response. In particular, the assessment of EM properties of different types of building walls commonly used in building construction, combined into one complete EM tool, is proposed. This is sought to be a valuable feature to be considered towards the integration with BIM-based simulation methods to provide unprecedented visualisation of the radio coverage within the building, allowing for the optimisation to meet specific facility radio requirements.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116435553","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}

Due to the LED faster response, these devices can be used for illumination and for optical wireless communications, simultaneously, making visible light communication (VLC) a hot research topic worldwide. As the VLC link is free space, big challenges arise in its implementation. To improve the VLC performance, this work addresses cooperative communications by employing an optical amplifier. In this context, conjugated polymer incorporated into organic-inorganic hybrids with high quantum yield (>50%) were synthetized and processed as planar waveguides. The maximum gain efficiency values observed were 0.73±0.01cm $mu mathrm{J}^{-1}$, which is among the best ones known for conjugated polymers and hybrid materials. The waveguides were tested in a VLC test-in-bed scenario, showing a signal amplitude improvement of 1 dB, establishing the proposed approach as a promising cost-effective solution for optical amplification in VLCs.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133297913","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}

Recently, a version of an Otto based device, baptized as Otto chip, was manufactured. Regression analysis procedures can be used to help the chip characterization by adjusting parameters of the model reflectance curve. However, as in any classical regression procedure, the initial guess must be close enough to the final solution to avoid convergence to a local minimum. An alternative approach to the classical regression procedure is the use of computational techniques inspired on swarms. Swarm intelligence, as this area of computer science is known, has successfully been used by engineers in various optimization problems. One prominent algorithm is the Particle Swarm optimization (PSO) that stands out for its low computational cost, simplicity of implementation and high efficiency on finding global optimum solutions. This paper describes the use of PSO in regression analysis of experimental SPR curves. It was shown that the PSO technique yields better results when compared with classical regression analysis methods.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"1 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126014734","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}
