Experimental demonstration of an optical artificial perfect magnetic mirror using dielectric resonators

In this paper, we experimentally demonstrate an artificial perfect magnetic mirror constructed from an array of cross-shaped dielectric resonators in the optical range. The TM_01δ mode of the cross-shaped dielectric resonator was exploited to provide a near-unity reflectivity and a near-zero reflection phase, mimicing a theoretical perfect magnetic conductor. A sample of the artificial mirror was fabricated using standard e-beam lithography and was further characterized, showing a strong agreement with simulated predictions.
