The Influence of Magnetic-Texture Treatment on Specific Properties of Iron-Sand EM Wave Absorption Material

Mix anisotropic uniaxial single-domain BaFe 12 O 19 particle into compound iron-sand foundation EM wave absorption material,with magnetic-texture treatment,we can find the absorption quantity increase from 19dB to 24.2dB,the absorption peak shifts from 9.25GHz to low frequency 8.6GHz,10dB bandwidth increase from 1.65GHz to 2.5GHz,there are two absorption peaks in the curve of A～f,matching thickness is also increased.This thesis is a preliminary discussion of mechanism of the action.
