ABSTRACT
Dielectric metamaterials are usually studied as low-loss media with magnetic response. However, control over the electric response is more promising for applications in photonics. Here we report an all-dielectric metamaterial with electric response. The structure consists of high-index dielectric rods arranged in a square lattice. We present a phase diagram that includes regions of metamaterials with magnetic and electric response. A metamaterial behavior is demonstrated for homogeneous ϵ-near zero modes, which are observed regardless of a lattice orientation and a structure boundary. The ϵ-near zero modes make it possible to enhance electric field intensity by two orders of magnitude, which can be used for applications exploiting light-matter interactions.
