Tunable negative permeability in an isotropic dielectric composite

Qian Zhao, Bo Du, Lei Kang, Hongjie Zhao, Qin Xie et al.
A tunable isotropic negative effective permeability is experimentally demonstrated in a three-dimensional (3D) dielectric composite consisting of dielectric ceramic cube arrays by temperature changing. It shows that a strong subwavelength magnetic resonance can be excited in dielectric cubes corresp ... [Appl. Phys. Lett. 92, 051106 (2008)] published Wed Feb 6, 2008.
