Bearing in mind applications in optical trapping, this work provides a set of finite series expressions for the BSCs, as an alternative exact method to analytically describe paraxial arbitrary order Bessel-Gauss beams. These beams are solutions to the Fresnel diffraction integral constructed from a Gaussianapodized Bessel beam. A comparison between finite series, 10-calized approximation (LA) and the time-consuming quadrature schemes are presented in terms of BSCs. It is shown that finite series and LA approaches agree with great precision. Taking into consideration its natural limitations, the LA approach computes BSCs with lower computational burden than the finite series, although the latter is an exact method which can also be extended to nonparaxial vector beams.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"29 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":"131337532","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}

Considering the toxic and explosive environments of oil industry, usual methods such as hot wire lead to unsafe measurements due to electric current on the sensor head. Thus, we propose a fiber Bragg grating (FBG) based sensor, which is chemically stable, intrinsically safe and has passive operation. In the experiments, it was chosen a range temperature between 25 and 45°C to guarantee the liquid state of three different elements analyzed: water, glycerin and mineral oil. As thermal conductivity depends on liquid temperature, the results obtained show that the device built is able to simultaneously measure temperature and thermal conductivity. Results show the feasibility of the proposed approach, where the temperature estimation using the FBGs resulted in a sensor with 0.9999 linearity and the thermal conductivity estimation of each liquid is in accordance with the results obtained in the literature for each of the tested liquids.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"27 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":"123151421","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}

These materials have good transparency and conductivity. Indium Tin Oxide (ITO) is a degenerate semiconductor material with high band gap, transparent in the visible range of the solar spectrum and belonging to TCO class. When nitrogen is added to the ITO thin film, it is formed a new semiconductor, ITON (or indium tin oxynitride). The properties and characteristics of this material depend on the nitrogen concentration that is incorporated in its structure. Characteristics such as band gap and resistivity differ if compared to ITO. ITON thin film also has a higher light response. In this work, Indium Tin Oxynitride films were fabricated by evaporation and PECVD techniques and electrical parameters were characterized. Incorporation of nitrogen into the film by plasma annealing with different temperatures $(140 ^{circ}mathrm{C}, 200 ^{circ}mathrm{C}, 260 ^{circ}mathrm{C}$ and $320 ^{circ}mathrm{C})$ could improve further the optical and electrical properties of the ITON films and thus making ITON film an ideal transparent and conducting material for opto-electronic applications. Substrates were silicon (75 mm, p-type, 1-10 ohm.cm) and optical three-inch glass wafers with 0.5 mm thickness. The thin films were analyzed with spectral response, IxV (current x voltage) and Hall effect analyses. The main objective of this study is the development of optoelectronic devices. The current versus voltage curve show the response of light. With the spectral response measures it is possible to verify that ITON based devices have higher quantum efficiency for the near infrared region. In conclusion, the ideal would be the application of these materials in sensors that operate in the infrared range.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"26 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":"125951760","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}

The framework platform, which relies on 6G fog enabled-delivery drones, terahertz communication, and artificial intelligence technologies, is described. The framework can be applied for highly cooperative, autonomous, and dynamic applications and systems such as supply chain’s last mile delivery of goods, harbour cranes, and maritime ports to help increasing access to goods in general, reduce traffic congestion and energy comsumption, and ease CO2 emissions from transportation.
