Digital Light Processing 3D-Printed Ceramic Metamaterials for Electromagnetic Wave Absorption
文献摘要：
Combining 3D printing with precursor-derived ceramic for fabri-cating electromagnetic(EM)wave-absorbing metamaterials has attracted great attention.This study presents a novel ultraviolet-curable polysiloxane precursor for digital light processing(DLP)3D printing to fabricate ceramic parts with complex geometry,no cracks and linear shrinkage.Guiding with the principles of impedance matching,attenuation,and effective-medium theory,we design a cross-helix-array metamaterial model based on the complex permittivity constant of precursor-derived ceramics.The corresponding ceramic metamaterials can be suc-cessfully prepared by DLP printing and subsequent pyrolysis process,achieving a low reflection coefficient and a wide effective absorption bandwidth in the X-band even under high temperature.This is a general method that can be extended to other bands,which can be realized by merely adjusting the unit structure of meta-materials.This strategy provides a novel and effective avenue to achieve"target-design-fabricating"ceramic metamaterials,and it exposes the downstream applications of highly efficient and broad EM wave-absorbing materials and structures with great potential applications.
