Interference -type absorbing materials are a material that can effectively absorb electromagnetic waves. The principle is mainly to use the interference effect between the microwave transparent media layer and the microwave absorption layer in the material, and convert the energy of the incident electromagnetic waves into thermal energy to absorb.

Common interference -type suction materials mainly include single -layer wave absorption membrane and multi -layer suction structure.

Single -layer suction membranes are mostly prepared with composite materials or metal particles mixed with polymer materials, which have a wide absorption band and good suction performance. Among them, composite materials mainly refer to the composite system of matrix materials and ripples. It can achieve the suction performance of a specific frequency band by regulating the proportion and type of the substrate material and the absorbing agent. Metal particles mixed polymer materials are mainly used by mixed metal particles and polymer materials, and the conductivity of metal particles can be used to achieve a suction effect.

The multi -layer suction structure often uses a layer -shaped structure with a certain air or medium, which can achieve a wider absorbing frequency band through interference effects between layers. Among them, the suction layer usually uses a suction agent, and the base layer mainly plays a role in supporting and fixing the absorbing layer.

The design and preparation of interference -type absorbing materials need to be considered in multiple factors, including absorbing frequency bands, suction performance, weather resistance, processability, etc. In practical applications, the appropriate interference -type suction material can be selected according to specific requirements, such as in the military field for stealth technology, or in terms of electromagnetic compatibility to inhibit electromagnetic interference.
