Radio Absorbing Composite Based on Square Resistive Patches
Tóm tắt
Solutions to the diffraction problems are used to calculate the effective permittivity of a composite material consisting of alternating planar arrays of square resistive patches shifted relative to each other in a dielectric layer. The relaxation character of the dispersion is demonstrated. The dispersion characteristic can be varied in wide ranges using variations in the parameters of the structure. Relative shifts of the arrays substantially affect the dispersion of permittivity of the structure. A ratio of the wavelength to the period of the structure that provides adequacy of a homogenization procedure is estimated.
