17,18 MGs are composed of small strips or slots printed or etched on the top layer of a dielectric substrate with a low profile, lightweight, and small losses characteristics, which allowed matched FM to radiate in the desired direction with a unitary efficiency. 2012 31:4095-4097 105Radi E, Formichi P, Battisti C. More recently, MGs are a subclass of electrically thin layer slabs to overcome the complex beam manipulation in inhomogeneous gradient metasurfaces that required more degrees of freedom, which have been introduced as an artificially subwavelength of periodic planar arrays to propagate a set of Floquet wave modes (FMs) by transferring surface waves to radiated waves that converted almost 100% for a single polarizable particle, 15, 16 low profile, and small losses characteristics allowed a few FMs matched to radiate in the desired direction. Younes Radi Anthony Grbic Metasurfaces have enabled unprecedented control over electromagnetic waves, providing new opportunities in areas such as wireless communications, energy harvesting. Parametric Enhancement of Radiation from Electrically Small Antennas Ahmed Mekawy, Huanan Li, Younes Radi, and Andrea Al Phys. He has made significant contributions in areas such as bianisotropic particles, optimal materials for strong light-matter interactions, and functional metasurfaces. 1 The structure of metasurfaces is a class of artificial materials engineered different shapes thin layers located in or on a dielectric to provide electromagnetic propagation as reflected arrays or transmitted arrays towards the desired directions, 2,3 the visible or the infrared to achieve various optical functions, 4,5 artificial magnetic conductor (AMC) reflectors using perfect electric conductor (PEC) for achieving wideband performances, 6,7 and also as radio frequency (RF) energy harvesting for obtaining ultrawideband applications.
