Abstract :
Investigation and application of extraordinary electromagnetic properties of metamaterials and nanocomposites becomes one of the most promising topics in last years. The problem of interaction between electromagnetic wave and magnetic nanoparticles is of essential interest. Resonance phenomena in 3D opal-based nanocomposites are studied here through frequency and magnetic field dependences of the transmission and reflection coefficients measured in millimeter waveband. Observation of magnetic antiresonance phenomenon is reported in a 3D-nanocomposite based on opal packages with embedded metallic magnetic particles. The antiresonance is seen at microwave frequencies of the millimeter waveband and it results in distinct maximum of the reflection or transmission coefficients.
