Radar absorbing properties of polyvinyl alcohol/Ni-Znferrite-spinel composite
نویسندگان
چکیده
The electromagnetic and radio-absorbing characteristics offerrite-polymer composites with conductive inclusions based on polyvinylalcohol are investigated. Ni-Zn spinel ferrite powder of 2000NN gradewith composition Ni 0.32 Zn 0.68 Fe 2 O 4 was used as filler. It is shown that theobtained effective absorbers in the frequency range 2-5 GHz peak reflection loss less than ~20 dB. Through analysis thepermittivity spectra permeability spectra, well calculatedreflection critical factors waveabsorption obtained established. Keywords: polymer composite, radio absorption, nickel-zinc ferrite,polyvinyl alcohol\
