Testing measurements of the real and imaginary parts of the dielectric permeability for a polypropylene film was performed. The main ways to improve the accuracy of measurements were determined. Theoretical models that describe the properties of nonlinear materials and numerical methods with program codes for studying the resonance properties of plasmon structures and metamaterials in the nonlinear mode of their operating were developed. Theoretical studies of electromagnetic wave diffraction on a periodic metal surface, which is covered with a thin layer of a dielectric, and on a metasurface with nonlinear inclusions were performed.
