Responses of the resonance frequency and Q-factor for EH211 and H011 on Ɛ and tanδ have been obtained. The procedure for obtaining estimates of Ɛ and tanδ from the resonant frequency and Q-factor of the resonator based on machine learning is considered, and the results of its use on the base of the data for resonances for the EH211 and H011 modes are given. Conclusions about the applicability of EH211 mode for measuring the dielectric constant and limitations for the ranges of measured parameters for the H011 mode are formulated.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"20 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":"114813888","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}

There no necessity to impose a restriction on the norm of the excitation currents in the array's elements because the amplitude of currents are given simultaneously with the amplitude RP. The respective Euler equation is derived for the optimization functional; the numerical procedure consisting of the convergent iterative process is developed. The numerical results for the different types of desired amplitude RPs are discussed.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"1 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":"130619822","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}

To solve the problem, the basic equations are reduced to the consideration of dynamic problems for some isotropic material. The obtained equations were solved using the Laplace integral transformation. Laplace transforms are found on the basis of the method of integral equations and are reduced to solving hypersingular integral equations. A numerical method for solving the obtained equations using the quadrature method is proposed. The Laplace inversion is performed numerically on the basis of pre-regularized formulas that allow the calculation of stresses with controlled accuracy. A study of the stress concentration near cracks under dynamic loads and falling waves was performed.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"228 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":"124514795","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}
