摘要
在铁砂基复合电波吸收材料中混入一定量介电型吸收材料 ,使基础材料吸收量明显增加 ,由 13dB增至 2 7dB ,匹配厚度仍保持在 1.2mm左右 ,混入一定量的电阻型吸收材料 ,吸收量由 13dB略增至 15dB ,匹配厚度明显增加达 1.4 8mm ,吸收曲线变得平缓 ,同时混入二种类型只收介质未产生积累效果 。
dielectric absorption medium into Composite Iron Sand-Foundation Radar Absorption Material, the absoptivity is greatly increased from 13dBto 27dB, the matching thickness is still 1.2mm; mix resistance absorption medium, the matching thickness is increased from 13dB to 15Db, the matching thickness is 1.48mm, the absorption curve become gentler; mix both mediums, accumulative effect is not produced, two absorption peaks can still be found between 7GHz to12BHz, the adding of mediums remarkably affects the absorptivity of the two absorption peaks.
