Magnetic metamaterials as perspective materials of radioelectronics
Electromagnetic properties of 3D-nanocomposites based of the opal matrixes containing particles of one or two transitive metals are investigated. Phase analysis of the nanocomposites is carried out. Microwave measurements are executed in the frequency interval of 26-38 GHz. Field dependences of the factors of passage and reflexion are obtained. Spectra of a magnetic resonance and antiresonance are restored. Frequency dependences of an amplitude of the resonance and antiresonance are obtained.
