Isotropic negative permeability composite, composed of BST-MgO dielectric cubes with high permittivity dispersed in the Teflon substrate with low permittivity, was designed and fabricated based on Mie resonance and the effective medium theory. Measurements and simulations showed that the dielectric composite exhibited a strong sub-wavelength magnetic resonance at the first Mie resonance and possessed isotropic negative permeability, which resulted from the displacement current excited in the cubes. The dielectric particle was equivalent to a magnetic dipole at the magnetic resonance, which could be adjusted by the size and permittivity of the particles. It may provide a convenient method to design isotropic metamaterials and invisible cloak at infrared and visible frequencies. 相似文献
