Abstract

We report a low frequency magnetic metamaterial super lens operating at 8.5 MHz. The super lens, composed of a slab of metamaterial with an isotropic effective permeability of negative unity, is capable of resolving two closely spaced magnetic sources that are indistinguishable in the absence of the lens, while simultaneously increasing the magnetic field strength observed in the image plane. Measurements of a prototype demonstrated the increased field strength and a resolution of 1/441 wavelengths, representing a new state-of-the-art in metamaterial-assisted near-field imaging.
