Fully carbon metasurface: Absorbing coating in microwaves

Abstract : The microwave-absorbing properties of a heterostructure consisting of an ordered monolayer of porous glassy carbon spheres were experimentally and theoretically investigated in the Ka-band (26-37 GHz) frequency range. The electromagnetic response of such "moth-eye"-like all-carbon metasurface at a normal incidence angle was modelled on the basis of long-wave approximation. Modelling parameters in the Ka-band were used to estimate and predict the absorption properties of monolayers in free space in the range 1-40 GHz. Experimental and theoretical results demonstrate that a metasurface based on porous glassy carbon spheres is an inert, lightweight, compact and perfectly absorbing material for designing new effective microwave absorbers in various practically used frequency ranges.
