Advances in Structural Design and High-Temperature Resistance and Broadband EMW Radar Absorbers Based on CMM Material

Abstract

Ceramic metamaterial (CMM) based metamaterials, which are artificial materials designed to have unique electromagnetic or thermal properties. These CMMs are often explored for their advantages like low dielectric loss, high-temperature resistance, and tenable performance, making them promising for applications in areas such as millimetre-wave devices, high-temperature sensors, and absorbers. Usually have the characteristics of lightweight, high specific stiffness and strength, controllable Poisson’s ratio designable anisotropy, etc. They can meet the requirements of multiple functions while meeting the load-bearing performance. They can be used as structural support materials, energy absorption materials, noise reduction materials, thermal conductivity materials, and biological materials, and have broad application prospects in aviation, navigation, medicine, and etc. Currently, the performance of common radar absorbers deteriorates dramatically at elevated temperatures, which limits their application in high-temperature environments. for broadband microwave absorption. In the CMM, which exhibits excellent electromagnetic (EM) wave polarization stability properties. This work may assist in the design and manufacture of a new generation of radars, ships, and aircraft will be evaluated using (HFSS) software (Vs. 15).
