The new algorithms for the investigation of fields in periodic structures with active and nonlinear inclusions were developed. The important for applications in the field of metamaterials the long-wavelength shift of the resonance strong in comparison with the resonance of one-element lattice was discovered. The analysis of absorptive bistability of planar metamaterial in the form of double concentric rings located on a nonlinear substrate was completed. Product Description popup.authors А.В.
