Abstract

Cancellation of the backscattering patterns (BSPs) of two main blocks of anisotropic 2-bit thin meta-coatings (MC) is numerically and experimentally investigated. Good matching of the simulation and measurement results of BSP in the area of central lobes for different planes and polarizations of irradiation is shown. In the principal planes, the central lobes of the BSP for co- and cross-polarizations are suppressed by 10-25 dB. The BSP in the sector of angles about ±40° is lower than that of the reference. In the diagonal plane, the expansion (approximately two times) of the BSP central lobe for co-polarizations and the bifurcation of this lobe for cross-polarizations (with a deep cancellation of up to 35 dB at normal incidence) are noted.
