MI/MS series low frequency magnetic conductive material is a kind of high permeability and high magnetic loss material covering 13.56M-8GHz wide band. It is filled with high loss absorbent and metal molecule, and ordered arrangement of absorbent can be made by specific process. It can suppress the multiple reflection of electromagnetic wave, absorb the signal of interference noise, and convert it into the form of heat energy, thus creating a clean electromagnetic environment.Protect the normal operation of the system.
