Initially, their application possibilities concentrated on communications. In recent years, a lot of research has shown the capability of using these crystals in the form of photonic crystal micro cavities (PCM) in gas sensing applications for e.g. environmental monitoring. Since these crystals exhibit so called photonic bands, they allow only certain frequencies to propagate through the structure while blocking other frequencies. These bands depend on a variety of parameters including the refractive indices forming the crystal structure; most importantly, they show a strong response towards refractive index changes. Thus, it is possible to create gas sensors with high selectivity that even react to the small refractive index changes of different gaseous analytes. These structures are often proposed to be used as chemical sensors, since they allow for very high Q values and thus very high selectivity. The performance of such sensors can be easily simulated with help of numerical approaches such as Finite Elements Method (FEM). Previous research that aimed at studying PCM sensors typically neglected losses due to signal attenuation in such simulations. In this paper we subsequently show how the Q values and the related gas sensing performance change with the imaginary refractive index of the crystal structure.","PeriodicalId":285890,"journal":{"name":"2017 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems (EESMS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132464162","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}

But these oil tanker accidents only account for a few percent of the total oil pollution worldwide and hide the regular pollution in important traffic zones like the Mediterranean and other oceans caused by oil drillings or illegal discharges. Due to very regular acquisitions from imaging radar on board satellites since the beginning of the 90's, statistical information about slicks is available all over the world oceans. From the first SAR satellites dedicated to research (ERS series, RadarSat-1) via European Envisat, TerraSAR-X, Cosmo Skymed or Canadian RadarSat-2 to the new European Sentinel series (namely Sentinel 1A, 1B and possibly 1C in the future) oriented towards services and applications, the expertise from the R&D community allows a much better oil spill monitoring nowadays. Oil spills appear as a dark patch on the SAR image. Nevertheless, detecting oil slicks and oil spills remains difficult, as other phenomena are also modifying the sea surface conditions: wind, sea state, currents, … In order to go beyond oil spill detection and tracking and for setting an efficient prevention system, one must also detect and identify the ships responsible of the oil discharges. For that purpose, synergetic approaches have been used, mixing the radar imaging inputs with met information and mandatory ship identification systems (AIS — Automatic Identification System) mainly. This effort is quite important as the vast majority of these pollutions occur near the coastal zones where 80% of the world population lives.","PeriodicalId":285890,"journal":{"name":"2017 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems (EESMS)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134549155","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}

When an impact occurs, it is important to check if a structural damage was originated at the impact location. On thin structures, impacts generate guided stress waves (Lamb waves) which can be analyzed to infer the actual impact position. A novel strategy to determine the Lamb wave direction of arrival, generated by an impact occurring in thin plate structures, is proposed in this paper. As already known, the wave mode propagation of GWs (i.e. Lamb Waves) along thin structures is characterized by a dispersive behaviour which could hinder an accurate estimation of the wave direction of arrival when monitoring the DToA associated to different sensors. Evidently, this is to be avoid in SHM (Structural Healt Monitoring) techniques. Overcoming this limitation is the aim of the paper, therefor a new estimation technique in the wavelet domain has been carried out for passive sensors. The proposed procedure, based on the CWT decomposition of non-linear signals acquired by three closely-located piezoelectrics transducers, causes a resampling of the time-frequency plane allowing to separate the wave components travelling at different velocities as well as to highlight the frequency dependence of the DToA. The multiresolution analysis has the advantage that the DToA among two different transducers can be computed multiple times, at different frequencies range, by applying the cross-correlation method in the CWT domain for each computed scale. In this way, the GW direction of arrival can be estimated making an averaging procedure across scales to the arc-tangent of the ratio between the DToA among specific sensors. The optimization of the transducers disposition on the plate has been also carried out and, in the end, experimental results are shown.","PeriodicalId":285890,"journal":{"name":"2017 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems (EESMS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121094046","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}
