Block Principle of Constructing and Estimating of the RCS Reduction of Nonabsorbing Broadband 2 Bit Anisotropic Digital Meta-Coatings

The block principle of constructing is considered and nonabsorbing 2 bit digital anisotropic meta-coatings (MC) with more effective reduction of monostatic RCSs (>10dB) within a wide frequency band when irradiated upon a wave of different linear polarizations are studied. Impedance and full-wave models and layouts of two main blocks of such MCs are developed. Calculated and measured levels of reduction of monostatic RCS of MCs' blocks are at least 12.5-13.5dB for different consonant polarizations within the band from 10.2 to 17.5 GHz and above. Calculated RCSs of impedance and full-wave models of the blocks are in good agreement with the experimental data.
