[0022] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 Shown: a bionic metamaterial with a scarab carapace helical structure, figure 1 It is a picture of the multi-layer structure of scarab carapace and a schematic diagram of its spiral structure. The fiber arrangement of each layer of the carapace is twisted at a certain angle relative to the previous layer to form a spiral arrangement structure from top to bottom. This structure can make ordinary wire poles The polarized electromagnetic wave is converted into a circularly polarized form, but the electromagnetic wave will be seriously lost during the conversion process. This loss has been considered a shortcoming of polarization conversion in the past, but it can be used in microwave absorbing materials to enhance absorption. The role of the unfavorable factors into favorable. Therefore, according to the helical structure of the present invention, the designed structural...
