The calculation of the interaction of elements metastructures based on the Gauss – Seidel method

The article is devoted to the calculation method of interaction metaelements. As a basis for the calculation is taken Gauss – Seidel method, which is used for solving linear algebraic equation with a diagonally dominant matrix. The proposed method operates matrices of self and mutual impedances, which form the overall matrix of linear algebraic equation. The method is applied to solve the problem of diffraction by metastructures – a thin layer of finite size, consisting of a double open rings. A mathematical model of the structure is based on the integral representation of the electromagnetic field. The convergence solutions for different values of the distance between the elements. The results of numerical modeling.
