The dielectic and magnetic losses of the inductive electromagnetic radiation in the object are large, and electromagnetic energy is converted into heat or other forms of energy. Absorption-type microwave absorption materials are divided into electro-loss type and magnetic loss type. In general, electrolytic materials absorb higher frequencies, while magnetically damaged materials absorb low frequencies more efficiently. If the two are combined, a wide frequency range of absorbent materials can be made. The electrode microwave absorption material is based on carbon (C) powder or metal particles to create a gradient dielectic ability absorbent material by thickness, depth change and changing the type of filler. Magnetically damaged microwave absorption materials are thin layers of material filled with magnetic materials such as ferride or niobium-based iron powder, such as epoxy polysulfur (chemical symbol: S), silicone rubber, urine, and fluorine elastic systems.
