Abstract: The rapid development of electromagnetic wave (EMW) communication technology has greatly aided the transmission of information and, as a result, the problem of high frequency electronic radiation has become increasingly serious. EMW absorbing materials have become important for solving this problem. The development of high-performance EMW absorption materials with “thin, light, wide, strong” characteristics is the focus and of EMW absorption. According to transmission line theory, we introduce the stealth mechanism of microwave-absorbing materials and summarize their preparation methods. Research progress on carbon-coated magnetic nanoparticle microwave absorbing materials is highlighted and their future prospects and development trends are then discussed. Finally, several suggestions are made for the applications and development of carbon-coated magnetic materials.
