Demonstration of Scattering Suppression by a Near-Zero-Index Metamaterial Composed of Dielectric Spheres

We demonstrate microwave scattering suppression by a near-zero-index metamaterial (NZIM) composed of dielectric spheres. The NZIM is designed based on numerical simulations, and is shown by near-field measurements that the medium with dielectric spheres of yttria-stabilized zirconia with the dielect...
