Our work relates to the use of metamaterials engineered to realize ameta-surface approaching the exotic properties of an ideal object not observedin nature, a "magnetic mirror". Previous realizations were based on resonantstructures which implied narrow bandwidths and large losses. The workingprinciple of our device is ideally frequency-independent, it does not involveresonances and it does not rely on a specific technology. The performance ofour prototype, working at millimetre wavelengths, has never been achievedbefore and it is superior to any other device reported in the literature, bothin the microwave and optical regions. The device inherently has large bandwidth(144%), low losses (<1 %) and is almost independent of incidence-angle andpolarization-state and thus approaches the behaviour of an ideal magneticmirror. Applications of magnetic mirrors range from low-profile antennas,absorbers to optoelectronic devices. Our device can be realised using differenttechnologies to operate in other spectral regions.
