Also algorithms for modeling of electromagnetic and acoustic wave propagation in such crystals are designed. Criteria for selection of optimal numerical algorithm parameters as well as periodical structure properties are proposed. Correctness of numerical simulations validated experimentally for one-dimensional case. Theoretical and experimental research of electromagnetic radiation propagation characteristics in multicomponent nanocomposites has been carried out. Experimentally was explored that in the case of tangential biasing of hexaferrite single crystal platelet the behavior of all obtained resonance branches for regular DSs has monotonic character in a multidomain area in the frequency range 25-57 GHz and noticeably depends on the type of DS (CDS, SDS). Splitting of eigenfrequencies of disk shaped magnetodieletric resonators was investigated in 40-110 GHz frequency range. Found that irradiation of linearly polarized radiation magnetic environment causes the formation of magnetic defect. A theoretical analysis of eigenpolarizations and eigenvalues pertaining to the Jones matrices of dichroic, birefringent, and degenerate polarization elements is presented. The methods of noise spectroscopy investigated the role of contact and the conditions under which the main role is played in the conductivity controlled channel, and also the noise level and the number of conduction electrons in the nanotube. The methods to scan objects by probes with different structure of local field which permit to study volume defects of sample more informatively due to variable (along vertical axis) instrument function of the probe have been offered.
