Perforate‐arrays as an all‐dielectric gradient index metamaterial for HPM lens

ABSTRACT All‐dielectric metamaterials have high potential for practical applications in high power microwave (HPM) area. In this article, a beam deflected flat lens made of all‐dielectric metamaterial is proposed. Owning to the angular symmetry of the element, the lens is able to neglect the incoming microwave polarization. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2859–2862, 2015
