Negative Permittivity and Permeability Metamaterials of Polymer-based Nanocomposite

ORAL

Abstract

Metamaterials with negative permittivity and negative permeability are a novel class of artificial materials. For large scale, light weight and deformable applications, it is compelling to develop flexible polymetric metamaterials. Accordingly, double negative metamaterials are created by incorporating Fe/Fe$_{3}$O$_{4}$ core-shell magnetic nanoparticles (MNPs) and conductive carbon nanofillers into the polyetherimide matrices. Dielectric tests and transmission-line perturbation method detect the negative permittivity and the negative permeability of the nanocomposites, respectively. This is attributed to the interaction between MNPs, the nanofillers and the polymer. By adjusting the component structures, the frequency range of the negative permittivity or permeability can be controlled, which is promising for the development of left-handed metamaterials.
