A Wave Absorbing Structure of an Analog Circuit Loaded with Magnetic Materials

A new composite analog circuit absorbing structure is designed by combining magnetic absorbing material with absorbing structure. Through adjusting the amplitude of electromagnetic wave, the total amplitude of low frequency band is reduced by 10 dB. Good electromagnetic absorption effect is achieved in the angle range of 0 ~ 70. It is expected that this structure will play a key role in the control of low frequency electromagnetic radiation.
