| Abstract: | Add SrFe12O19 single domain particles to two kinds of ferrite EM wave absorption materials , then treat them with parallel and vertical magnetic field , research on the absorption properties in the range of 8～12 Ghz . We can fmd when treated with vertical magnetic field , the maximum absorption quantities increases from 16dB and 14dB to 20dB and 25dB respectively; when treated with parallel magnetic field , magnetic anisotropy is induced , we can get the best absorption properties in the preferred orientation , the maximum absorption quantities is 23dB and 27dB respectively, matching thickness increases . This is a discussion about the action mechanism. |
