铁氧体及其复合吸波材料的研究进展

Absorbing materials can not only reduce electromagnetic pollution, but also achieve the purpose of military equipment stealth, which require the characteristics of "thin, light, wide, strong". Ferrite absorbing materials have good impedance matching, strong absorption, and have been studied early and used many times. However, the disadvantages of high density, narrow absorption band and poor thermal stability limit the application of ferrite absorbing materials. By substituting ions, designing micromorphology, synthetizing composites of ferrite and carbon materials, polymer materials or MXene, the comprehensive properties of ferrite absorbing materials can be improved effectively. In this paper, main methods to improve the properties of ferrite absorbing materials and the research progress in recent years are summarized, and the further research direction is prospected.
