Exceptional electromagnetic interference shielding properties of ferromagnetic microwires enabled polymer composites
Journal of Applied Physics
We present systematic studies of the electromagnetic interference ͑EMI͒ shielding and microwave properties of a new class of shielding material, i.e., the ferromagnetic microwires-embedded polymer composites. We show that at 1-2 GHz the shielding effectiveness ͑SE͒ of the continuous-wire composite reaches a high value of 18 dB ͑98.4% attenuation͒ for a very low filler loading of 0.024% and a thickness of 0.64 mm. The normalized SE of this new composite is about 70 times higher than that of thedoi:10.1063/1.3471816 fatcat:6wvqqotq5na3toy57gnwb5xhpy
