High-temperature broadband wave-absorbing metamaterial for 3D printing as well as preparation method and application of high-temperature broadband wave-absorbing metamaterial
The invention discloses a high-temperature broadband wave-absorbing metamaterial for 3D printing and a preparation method and application thereof, the high-temperature broadband wave-absorbing metamaterial for 3D printing comprises n * m unit structures arranged in an array, n > = 2, and m > = 2; the unit structure is one of the following four structure types. According to the structure of the high-temperature broadband wave-absorbing metamaterial for 3D printing, taking the ceramic precursor as a raw material, and printing by adopting a 3D printing technology to obtain a ceramic biscuit; and pyrolyzing the ceramic biscuit to obtain the high-temperature broadband wave-absorbing metamaterial. The high-temperature broadband wave-absorbing metamaterial structure for 3D printing can be suitable for improving the high-temperature wave-absorbing performance of 3D printing precursor conversion ceramic, and equivalent dielectric parameters and impedance matching of the ceramic with the intrinsic dielectric real part within the range of 8-50 and the imaginary part within the range of 5-30 can be adjusted through structural parameter optimization. And broadband coverage of an X wave band between 25 DEG C and 700 DEG C can be realized under a single thickness.
