The Scattered Field Phasing Effect of Cylindrical Digital 1 Bit Anisotropic Meta-covers

摘要

The scattering patterns formation features of the cylindrically curved digital 1 bit azimuthally coded anisotropic meta-covers are considered in the paper. The simulation results (using HFSS) of mono- and bistatic RCSs on co- and cross-polarizations within the frequency range from 8 to 19 GHz for models with different small azimuthal size (relative to the wavelength) of 1 bit modules are given. The modules are consisted of meta-particles as figure-eights arranged on a thin shielded substrate. The scattered field phasing phenomenon when the RCS of meta-covers on co- and cross-polarizations becomes higher than the RCS of the reference metallic cylinder on co-polarization is investigated. The physical interpretation of the effect mechanism is demonstrated.
