Magnetic nanoparticles for tunable microwave metamaterials

摘要

Commonly, metamaterials are electrically engineered systems with optimized spatial arrangement of subwavelengthsized metal and dielectric components. We explore alternative methods based on use of magneticinclusions, such as magnetic nanoparticles, which can allow permeability of a composite to be tuned from negativeto positive at the range of magnetic resonance. To better understand effects of particle size and magnetizationdynamics, we performed electron magnetic resonance study on several varieties of magnetic nanoparticles anddetermined potential of nanoparticle use as building blocks for tunable microwave metamaterials.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
