Laser beams possess good focusing capabilities and provide the possibility to perform chemical reactions, including metal oxidation, locally and with high spatial resolution. With the use of laser beams with frequency modulation, a synergistic effect between the laser heat actions and the vibrations induced by the laser pulses is created. Thus, the coefficient of diffusion increases considerably as result of the nonstationary strain-stress state of the material. The synthesis of ZnO/Cu semiconductor-metal nanocomposite on the surface of brass samples is described. As a result of pulse-periodic laser treatment, anisotropic quasi-one-dimensional structures - zinc oxide nanowires - are formed on the material surface, i.e. on the conductive metal substrate. By using free-form diffractive optics to shape the laser beam, it is possible to control the chemical processes on the material surface. The resulting material structures are promising for sensor applications due to the sensitivity of ZnO to various chemical agents, biocompatibility, and the possibility of modifying it by various methods.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"27 19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124993207","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}

This task is of importance for the development of a short carbon fiber reinforced polymer material model, which requires precisely counting and measuring the fibers in a sample to determine the structural characteristics of the material. To automate the process of counting and measuring fibers, a neural network architecture called Mask R-CNN was chosen, which is designed to implement computer vision techniques such as: object identification, segmentation and quantification of instances. The selection of this type of architecture was due to the advantages of giving the masks for each instance, which allows obtaining approximate measurements of the fiber geometry. Due to the unavailability of fiber image data, the virtual imaging technique was chosen. Artificial images of short carbon fibers were recreated using the open API NX. A virtual data set with different fiber layouts was created. The results obtained in the test phase are good, for small numbers of fibers and with sparse clusters. There are still some problems in fully identifying the geometry of fibers that overlap with other fibers, which is a challenge to solve in future work.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132733819","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}

This research work investigates optical amplification action in a 2D Photonic Crystals (PhCs) based metasurface with variable radius even-positioned PhC-cavity. Two optical signals are used, i.e., data signal coupled into the optical structure using the phenomenon of the Guided-mode-resonances (GMR) and a pump signal index-guided into the optical structure. The pump signal is used to amplify the data signal and the PhC-cavity is used for spectral tuning of the device operating in the near-infrared (NIR) range. The designed structure comprises of an optical waveguide packed in between the layers of a substrate and cladding. The design and analysis of the proposed device is performed using Finite-difference Time-domain (FDTD) approach in an open-source software package. The investigated results present optical amplification action for a PhC-cavity of radius i.e., greater than the standard radius of the PhC-elements used in the investigated structure. Moreover, as a concluded fact, PhC-cavity nearer to the symmetric point of the optical structure will greatly influence the amplification phenomena and tuning of the GMR modes. The designed device can be used in applications relating to optical transistors, filters, and integrated circuits.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134579501","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}
