As an attractive for applications, a Littrow scheme of double-ray resonant reflection by a periodic metasurface is investigated to provide a strong light-matter interaction controlled by light. We assume that the metasurface is constructed as an array of nonlinear silicon nanodisks located on a metal substrate. The excitation of a Mie-resonance that has a specific symmetry of field distribution used in mobile antennas is supposed. The ratio of values of non-specular and specular reflectance can be controlled by tuning the incident wave intensity.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122612788","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 proposed approach requires the segmentation of the input signal into parts that may overlap. The Prony's method is then applied for each individual part. The mean or median estimation of the true values can be applied either to the eigenvector itself, or to the final values of complex amplitudes and frequencies. All possible combinations of the above-mentioned approaches were tested for the current paper. Results of the estimation of the amplitudes and frequencies were analyzed separately from the results of initial signal reconstruction. The proposed method was compared with the standard Kumaresan-Tufts approach and standard eigenvector approach.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133105780","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}

Our goal is to find the best parameters of the antenna, using the numerical experiment, to achieve desired radiation parameters: well matching to the open space; phase controlled narrow-beam; wide-band. There was designed phase controlled and two beams patch antennas at 7.6 GHz and 7.8 GHz respectively. Phase controlled antenna was archived by cutting patch antenna by half.

The task takes on particular importance when considering dust as a means of transportation for various viruses and infections. The technical solutions we are considering boil down to the implementation of precision photometric measurements of light scattering by dust particles in liquid samples, the concentration of dust in which we increase to reliably measurable by photometry. The carried out research made it possible to formulate problems and propose solutions for a monitoring network. Technical solutions are implemented in working models and tested in urban dustiness of Tbilisi.
