AI Technical Summary
The composite material core structure of existing absorbers has low load-bearing efficiency, especially when the relative density is less than 5%, it is prone to buckling, making it difficult to achieve wide-bandwidth, high-intensity absorption.
The structure of the grid absorber includes a base plate layer, a core layer and a panel layer connected in sequence. The core layer is composed of first and second core groups arranged in an alternating manner. The core body includes an electromagnetic loss absorbing component and a metamaterial absorbing layer, forming a multi-level hybrid core structure. The electromagnetic loss absorbing component and the metamaterial absorbing layer are respectively connected to the base plate and the panel.
It significantly enhances the synergistic effect of absorption performance and load-bearing performance, achieving high-intensity electromagnetic wave absorption capacity and structural load-bearing capacity, especially exhibiting excellent absorption performance under L, S, C, X, Ku bands and multi-angle incident conditions.
