摘要
Abstract
We can make superior absorption materials by using iron-sand (magnetite ore) tailings. In the range of 8～12 GHz , the absorption quantity is 18 dB, matching thickness is 0. 58 mm , 10dB bandwidth is 2.5 GHz. The absorption quantity increases to 28.4 dB when the material is phase-transition by thermal treated . Replacing a part of iron-sand tailings with spinel-ferrite , the absorption peaks move to high frequency; Absorption quantity and bandwidth are greatly increased when adding to it with transition metallic ions , A=19 dB , 10dB bandwidth is 3.5 GHz; adding mediums with different electric characteristics can also improve its absorption prop erties , then the results distinguish greatly.关键词
