Background. This work is devoted to inverse problem of electromagnetic characteristics reconstruction of isotropic and anisotropic diaphragms. The aim of study is to develop numerical-analytical methods of solving inverse problems.
Materials and methods. We consider inverse problem: inverse problem of permittivity and permeability tensors reconstruction of multi-sectional diaphragm. The problem is devoted to the boundary value problem for Maxwell’s equations.
Results. We obtain numerical-analytical methods of the solution of the inverse problem.
Conclusions. The numerical methods of solving the inverse problem and numerical results can be used in practice to reconstruct electromagnetic characteristics of modern materials.
