Abstract
Devices and methods for magnetic imaging and / or irradiation are discuseed. The magnetic fields produced for imaging and / or irradiating, as well as the associated magnetic field, can be focused using one or more magnetic metalens devices. Variations of magnetic metalens devices may be made of cubic unit cells equipped with capacitor-bearing conductive loops printed on an inside face of a dielectric of the cube(s). Some variations may also include a series capacitor equipped with a matching network that includes at least one series capacitor. Other variations may also include a tapered microstrip.
