2-18 GHz full-frequency absorption and easy-to-manufacture ultra-light wide-angle wave-absorbing metamaterial based on cheap and easily-obtained carbon conducting film and manufacturing method of ultra-light wide-angle wave-absorbing metamaterial

The invention provides a 2-18 GHz full-frequency absorption and easy-to-manufacture ultra-light wide-angle wave-absorbing metamaterial based on a low-cost and easy-to-obtain carbon conducting film and a manufacturing method of the ultra-light wide-angle wave-absorbing metamaterial, and belongs to the technical field of functional composite materials. Comprising a first dielectric substrate, a first carbon-series conductive film structure array layer, a second dielectric substrate, a second carbon-series conductive film structure array layer, a third dielectric substrate and a third carbon-series conductive film structure array layer which are sequentially stacked from bottom to top, and the first, second and third carbon series conductive film structure array layers are all formed by periodically arranging discrete carbon series conductive film patches. According to the invention, through the coupling of the multiple layers of carbon series conductive film periodic unit arrays, the wave-absorbing metamaterial
