Metasurface based on single-turn planar spirals with non-reflective absorber property in the microwave range

The theoretical calculation, modelling and experimental study of the metasurface based on single-turn planar spirals for obtaining maximum absorption in the absence of electromagnetic wave reflection in the microwave range have been carried out. The calculation of the structural parameters of the absorbing metamaterial was carried out for two glass-textolites – Arlon AD255C and Taconic TLY. The results of the studies confirmed the possibility of using the proposed structure as a non-reflective absorber of electromagnetic waves.
