【摘要】 根据雷达工作原理和等效电路法,通过理论计算得出了提高吸波材料的吸波性能所要满足的两个条件:第一,为了尽量减少雷达波在涂层表面的反射,要使得吸波涂层的相对复介电常数(εr)和其相对复磁导率(μr)尽量接近;第二,为了尽可能多地使进入到涂层内部的雷达波受到衰减,要尽量提高吸波材料的ε"r.r和μ"更多还原

【Abstract】 <Abstrcat> Based on the operating principle of radar and the simple equivalent electric circuit, the matching condition of electromagnetic parameter and the relationship between electromagnetic parameter and capability of electromagnetic absorption are discussed. The results indicate that (1) the material with ε_r=μ_r should be used as microwave absorber. (2) ε~"_r and μ~"_r of the microwave absorber must be increased.更多还原
