Abstract

Transmission of microwaves through a composite plate containing Fe nanoparticles in an epoxyamine matrix, as well as reflection of waves from it, has been investigated. The experiments were performed at the frequencies from 26 to 38 GHz in the magnetic fields up to 12 kOe. The ferromagnetic resonance line in the composites with the weight fraction of Fe particles from 10% to 30% has been studied. The magnetic field dependence of the microwave power dissipation has been plotted. Field dependence of the transmission and reflection coefficients have been calculated, as well as qualitative, and in some cases quantitative, agreement has been obtained. The penetration depth of microwaves into the composites has been analyzed. Spectrum of the FMR has been constructed. Results of interaction of microwaves with Fe nanoparticles are discussed taking into account magnetic properties and composite structure.

期刊介绍： This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
