Light broadband metamaterial wave-absorbing structure based on C-shaped interlayer

The invention provides a light broadband metamaterial wave-absorbing structure based on a C-shaped interlayer, and the light broadband metamaterial wave-absorbing structure based on the C-shaped interlayer is sequentially provided with a first composite layer, a second composite layer and a reflecting layer along the propagation direction of electromagnetic waves, the first composite layer comprises a sandwich structure formed by a plurality of wave-transparent layers and skin layers which are arranged in a staggered manner; the second composite layer comprises resistive film layers and wave-transparent dielectric layers which are arranged in a staggered manner; and a reflecting layer is arranged on the lower surface of the lowermost wave-transparent dielectric layer. Through the design of the C-shaped sandwich structure, the wave-absorbing performance of the wave-absorbing sandwich structure in a high-frequency (Ku) wave band can be greatly improved, and the defect that when the thickness of the skin is larg
