| 摘 要： | 根据吸波材料电磁反射系数的传输线理论进行优化设计是微波吸收材料研究的重点,微波吸收材料的吸波效果与其电磁参数(介电常数与磁导率)和材料厚度密切相关,电磁参数测量的准确性与微波吸收材料厚度制作的精确性,对微波吸收效果有很大的影响。通过理论计算分析,探讨了电磁参数测量误差对微波吸收材料优化设计结果的影响,并讨论了微波吸收体厚度制作误差对微波吸收材料吸波效果理论计算值对优化值偏离的影响。

| Abstract: | Based on the transmission line theory of electromagnetic wave reflection coefficient,optimizing design for microwave absorber is of great importance.Absorption effect of radar absorbing material(RAM) is closely related to its electromagnetic parameters(including dielectric constant and permeability) and its thickness.Measuring accuracy of electromagnetic parameters and machining precision of radar absorbing material thickness have great impacts on absorption effect.Effects of measuring error for electromagnetic parameters on the optimum design results of radar absorbing materials are investigated with theoretical calculation analysis,and the effect of machining error for radar absorbing material thickness on the deviation from theoretical absorption and optimum result is discussed. |
