Integral equations system defining densities of electric currents on linear dipoles and equivalent magnetic currents in coupling holes were formulated based on boundary conditions on dipoles and continuity conditions for tangential components of magnetic fields in the coupling holes. Quasi-one-dimensional equations uniquely determining currents in the system elements were obtained by using physically based transition from obtained two-dimensional integral equations. The thin linear impedance dipoles may have irregular geometric and electrophysical characteristics along their length and the narrow slots may be arbitrary cut in surfaces of two electrodynamic volumes. Combined multielement dipole-slot structures may have the same properties.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"22 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":"123605889","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 bistable characteristics of the metasurface can be effectively controlled by changing illumination conditions.

The Kirchhoff's formula is used to represent the solution and the problem is reduced to time-domain boundary integral equations (TDBIEs) that contain Cauchy data as unknown values. By applying the Laguerre transform, the sequence of systems of boundary integral equations (BIEs) is obtained. It depends only on spatial variables. Besides, it is proved that matrix operator composed with boundary operators corresponding to retarded single layer and double layer potentials is elliptic in special functional space. This property is the basis for the development of the efficient numerical method as composition of the Laguerre transform and boundary element method. The results of numerical experiments for model problems with dynamic boundary conditions demonstrate the dependency of solution on impedance parameter change. In addition, error and estimated order of convergence confirm the correctness and efficiency of proposed approach.","PeriodicalId":150897,"journal":{"name":"2021 IEEE 26th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"3 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":"125723758","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}
