Coherent meta-magnetics: collective resonances and disorder-induced transitions

Abstract

Artificial materials with a strong magnetic response at high frequencies are becoming increasingly important in a wide range of applications and devices, ranging from super-lenses to NMR sensing. Metamaterials, crystalline ensembles of sub-wavelength resonators, promise to provide magnetic response at prescribed wavelengths over a wide range of the electromagnetic spectrum. Here, we demonstrate that magnetic metamaterials belonging to the recently identified class of coherent metamaterials, exhibit strong magnetization of collective nature that is absent in an isolated unit cell resonator. As a result, this type of metamaterials is extremely sensitive to disorder leading to a rapid disappearance of the resonant magnetization.
