Design of All Dielectric Metasurface Absorber Based on High Permittivity Ceramics

This paper uses high-permittivity ceramics to design an all dielectric metasurface absorber, which can form a good absorption effect through dielectric resonances. The absorption efficiency can reach over 90 %. This design uses an integrated connected structure, which facilitates the use of mature technologies such as solid-state sintering or 3D printing for production. Ceramic materials have advantages such as high temperature resistance, oxidation resistance, corrosion resistance, and high power resistance. This design method can adjust resonance to achieve absorption of different bandwidths and frequencies, and has potential application value.
