In this paper, the effect of the geometrical parameters of an electrical ring resonator(ERR) on the total absorptivity of metamaterial absorbers is analyzed. In particular, the effect of electrical ring resonator parameters, dielectric layer(spacer) thickness and electrical ring resonator thickness on the absorber of metamaterials are analyzed in detail. On this basis, the orthogonal experiment is set up to analyze the combined effects of several parameters and finally obtain the theoretical absorptivity of metamaterials. Based on the above results, the principle prototype of two metamaterial absorbers is prepared. The results show that the narrowband absorptivity of the prototype is higher than 98%, which provide guidance for the design of high performance absorber.
