EMI wave absorber sheet refers to a kind of material which can absorb the electromagnetic wave energy projected on its surface. The wave-absorbing sheet in electronic equipment can absorb the leaked electromagnetic radiation, to achieve the purpose of eliminating electromagnetic interference. EMI wave absorber sheet is mainly used to suppress electromagnetic interference, improve the accuracy of radar direction finding and ranging.It also can be used to prevent electromagnetic interference, electromagnetic radiation and waveform shaping of microwave devices and equipment. It is very suitable for microwave anechoic chamber, electromagnetic compatibility chamber, absorption load, attenuator, radar wave RCS Reduction, etc. It has the advantages of thin thickness, light weight, wide absorption band, high absorption rate, etc. It can be customized according to the drawing.
