Title: Manipulating electromagnetic responses of metal wires at the deep subwavelength scale via both near- and far-field couplings

A hybrid coupling model containing both near- and far-field couplings is developed for radiating two-resonator structures. We demonstrate that the near- and far-field couplings make distinguished contributions to electromagnetic responses. Compared to the classical electromagnetically induced transparency configurations, the presence of far-field coupling provides more flexibility in tuning lineshapes. Planar metamaterials composed of metal wires are designed based on this model, and various electromagnetic responses are experimentally observed.
