The absorbing property of radar absorbing material is usually expressed by the power reflection coefficient of the absorbing material toward the electromagnetic wave.

雷达吸波材料的吸波性能通常以吸波材料对电磁波的功率反射系数来表示。

The formulae of reflecting coefficient are derived from the theory of electromagnetic field for arbitrary incident electromagnetic wave to radar absorbing material.

从电磁场理论出发，推导出了电磁波以任意角入射时雷达吸波材料的反射系数公式。

Microwave Absorbing coatings with different thickness were prepared by fiber X as the Absorbing agent, and the reflecting attenuations of the radar wave were researched.

采用X纤维为吸波涂料的吸收剂，制作不同厚度的吸波涂层，测试相应的雷达波反射衰减值。
