Abstract
In this paper, we propose an isotropic metamaterial lens (meta-lens) with an operational frequency of 8.5 MHz for imaging applications. The cubic unit cells, composed of inductor-and and capacitor-loaded split rings, are aligned in a periodic three-dimensional dimensional lattice. The meta-lens provides an effective isotropic permeability eff = 1 at 8.5 MHz. The lens enhances the evanescent fields, producing strong magnetic fields and sharp subwavelength resolution at the image plane. Measurements of a fabricated meta-lens were found to match full-wave simulations.
