EMC/EMI(Shielding / absorption / suppression)

Microwave absorbing material is a kind of functional composite material which mainly absorbs electromagnetic wave. It can eliminate the back and forth reflection of electromagnetic wave in the shielding cavity, reduce the interference of clutter to its own equipment, and effectively prevent electromagnetic radiation from disturbing and injuring the surrounding equipment and personnel. It is an advanced means to eliminate electromagnetic pollution. The application of absorbing materials in electronic equipment can absorb the leakage of electromagnetic radiation, which can achieve the purpose of eliminating electromagnetic interference. According to the propagation law of electromagnetic wave in medium from low permeability to high permeability, high permeability ferrite is used to guide electromagnetic wave. Through resonance, a large amount of radiation energy of electromagnetic wave is absorbed, and then the energy of electromagnetic wave is transformed into heat energy through coupling.

High permeability absorbing materials not only need high permeability real part u ', but also high permeability imaginary part U "(commonly known as" high magnetic loss "). Analysis principle:

The higher the real part of permeability can increase the magnetic flux of the cluster interference source, and the higher the imaginary part of permeability can effectively convert the cluster magnetic flux into the latent heat consumption, so as to reduce or eliminate the electromagnetic radiation interference harm of the interference source. Data analysis shows that the higher the real part of permeability, the better the relative low frequency absorption effect and the wider the effective absorption frequency.
