针对传统吸波材料在雷达波S波段的吸波性能较差,以多种铁镍磁性合金粉为吸波剂,硅橡胶为基体,制备不同组分的吸波材料。采用HP8722ET矢量网络分析仪对吸波材料的电磁与吸波性能进行了研究。结果表明:吸波材料的最小反射率为-19.5 dB,其对应的峰值频率为2.5 GHz,有效带宽(小于-8 dB)为1.9 GHz;吸波材料在S波段表现出优异的吸波性,具有良好的应用前景。
Aiming at the poor absorbing performance of the traditional absorbing materials in the S wave band of the radar wave, a variety of iron-nickel magnetic alloy powders are used as the absorbing agent and the silicon rubber as the matrix to prepare the absorbing materials with different components. The HP8722ET vector network analyzer was used to study the electromagnetic and microwave absorbing properties of microwave absorbing materials. The results show that the minimum reflectivity of the absorbing material is -19.5 dB, the corresponding peak frequency is 2.5 GHz and the effective bandwidth (less than -8 dB) is 1.9 GHz. The absorbing material shows excellent absorbing ability in the S band, Has good application prospects.
