Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0042] Such as figure 1 As shown, the present invention provides a single-pass-band double-sided wave-absorbing composite metamaterial, including a dielectric substrate 100 made of a non-conductive material and four periodic metamaterial structural layers embedded in the dielectric substrate; The four layers of periodic metamaterial structure layers are in order from top to bottom, as shown in figure 1 In the Z direction, respectively, the resistive thin film layer 102, the first metal patch layer 103, the second metal patch layer 104 and the third metal patch layer 105; the distance between each periodic metamaterial structure layer from the surface of the dielectric substrate Not the same; the single-pass-band double-sided wave-absorbing composite metamaterial is virtually divided into a plurality of periodically arranged square unit structu...
