| 摘 要： | 通过数值分析确定了单层电损耗吸波材料理想电磁参数,探讨了单层吸波材料的吸波机理.分析表明:单层吸波材料要实现宽频吸收,其电磁参数必须具有频散效应,即随电磁波频率的升高电磁参数有规律的降低,其中ε′·μ′与f2成反比.以羰基铁粉/聚氯乙烯吸波贴片为实例验证了理论分析结果,讨论了常规单层吸波材料性能的影响因素.

| Abstract: | The optimal complex permittivity of single layer ohmic lossy radar wave Absorber was explained in theory.The explanation revealed the Absorbing mechanism of single layer radar wave Absorbing materials(RAM).Single layer materials' electromagnetic parameters must decrease with frequency by rule to acquire strong Absorption in wide wave band.Iron powder/PVC RAM were tested and the results accordded with the theoretical analysis.The factors which influenced the performance of conventional single layer RAM are discussed. |
