Abstract :
Metasurfaces are thin planar electromagnetic structures that are capable of controlling electromagnetic field behavior beyond the capabilities of frequency selective surfaces or analogous structures composed of a uniform material. Metasurfaces have several advantages over volumetric metamaterials, such as compactness, low losses and ease of fabrication (C. L. Holloway, E. F. Kuester, J. A. Gordon, J. O´Hara, J. Booth, and D. R. Smith, IEEE Antennas Propag. Mag., 54, 2012, pp. 10–35). Recently, and for these particular reasons, metasurfaces have been steadily replacing volumetric metamaterials and are thus gaining wide attention in the literature.
