In the course of work for the I-th stage set goal was made with the following results: 1) experimental studies of resonant absorption of electromagnetic waves in the manganite - perovskite La0.7SrхMnO3 and found that at room temperature effective magnetization increases with a "parallel" geometry experiment with increasing concentrations of Sr; 2) numerical simulation of the spectral properties of the lens of the copper and magnetodispersion wires, and have been found periodically spaced frequency regions with high pass, which comply with the Fabry-Perot resonance, i. e., the lens holds energy channeling mode; 3) numerical simulation of the spectral properties of the magnetophotonic crystal of millimeter frequency range near magnetoresonance absorption in the magnetic layer of the crystal was held, resulting in a series of spectra obtained by transmission of electromagnetic wave through a one-dimentional MPC analyzed , and it is shown that the band gap of MPC's strong frequency dispersion of magnetic permeability layer ferodielectric (near FMR arise "secondary bands" transmission. The findings of the research I - th stage results are presented in the form of papers in international conferences and will be applied in the further stages of research.
