Abstract
The design of a planar negative refractive index lens operating at 3 GHz and constructed from an array of dielectric resonators and continuous metal strips is presented. The dielectric resonators provide negative permeability and largely determine the lens operating frequency. The metal strips on printed-circuit boards, provide negative permittivity. By strategic choice of the printed circuit board substrate material, the lens permittivity can be adjusted without impacting the permeability. Preliminary experimental and simulation results are used to demonstrate partial focusing of loop probe near-fields.
