Abstract
In the last decades, metamaterials and metasurfaces has dramatically emerged as a fundamental research topic in electromagnetism due to the wide range of possible applications [1]. They have been proved useful for absorbing the undesired impinging e.m. energy and, thus, reducing an object radar cross section. Moreover, they can achieve exotic behavior, as negative refractive index, negative permeability and permittivity, and perfect lensing property. In the relatively low frequency regime (1-100 MHz), magnetic metasurfaces have become a powerful tool to enhance the performance of wireless power transfer devices as well as to increase the signal-to-noise ratio in MRI radiofrequency coils.
