Abstract
|
In this work, the effect of doping by Ag and stirring time on the structural, dielectrical and magnetical properties of Ag/Zr0.9Ni0.1Oy nanocomposite is considered. For all samples, the transmission electron microscopy (TEM) analyses show that doped Ag nanoparticles are dispersed randomly in the host dielectric. The permittivity and permeability behaviors of samples were investigated. Also, by changing the size of Ag, variation of permittivity and permeability changes are introduced. It was found that samples with 45, 47 and 50 wt% Ag exhibit the double negative (DNG) properties. Simultaneous negative permittivity and negative permeability were tunable in the Ag/Zr0.9Ni0.1Oy nanocomposites. We believe that the this work will be useful to all those interested in preparation of random nanocomposite DNG metamaterial.
