Polycrystalline iron fiber absorbing material is a material with a good suction performance and is usually prepared by polycrystalline iron fiber.

1. Material structure: Polycrystalline iron fiber suction material is usually composed of nano -level polycrystalline iron fibers, with a specific appearance and structure. Its suction performance depends on factors such as fiber appearance, relative arrangement between fibers, and density of materials.

2. Waveting mechanism: The suction mechanism of polycrystalline iron fiber suction materials mainly includes the process of energy loss, reflection and scattering between electromagnetic waves and materials. By selecting the appropriate material structure and process parameters, the effective absorption of electromagnetic waves for specific frequency bands can be achieved.

3. Frequency band selection: The absorbing frequency band of polycrystalline iron fiber suction materials can be regulated as needed. Common absorbing bands include X, KU, K and KA bands. For different application scenarios, you can choose different frequency bands and material combinations to achieve the best suction effect.

4. Preparation process: The preparation process of polycrystalline iron fiber suction materials involves the preparation of fiber, the appearance control of the material, and the modification of the material. The current commonly used preparation methods include soluble gel method, electrochemical deposition method, and gas deposition method. By optimizing process parameters, the suction performance and stability of the material can be improved.

5. Application field: Polycrystalline iron fiber suction materials have extensive application prospects in the fields of military, aerospace, electronic communications, and radio waves. It can be used to prepare suction coating, wave absorption structure and wave absorption material to achieve effective shielding and absorption of electromagnetic waves.
