Study on Circuit Analog of Radar-absorbing Structure Composites

研究了电路模拟结构(电路屏)在结构吸波复合材料中应用的可行性。重点研究了电路屏结构尺寸、电路屏所处位置及复合材料体系各层中吸收剂配比对吸波特性的影响,结果表明,电路屏在雷达吸波材料中起到了以下的作用:电路屏能引起入射电磁波与反射电磁波的干涉,起到又一反射屏的作用;电路屏的加入能增大吸波结构的表面输入阻抗。通过合理的设计电路屏及使电路屏结构尺寸与吸波结构中的介质层相匹配,电路模拟结构可以有效地提高吸波结构的吸波性能。

The size of the circuit analog, the location of the circuit analog, the absorbent, content of composite had been investigated. It has been found that the circuit analog play the role of reflection screen and can be used to adjust the radar-absorbing structure composite surface-resistance, improve the EM wave energy attenuation property of the radar-absorbing structure composite and widen the work frequency band width of EM wave . Therfore, through rational composite material design and preparation , the radar-absorbing structure composite with circuit analog can have good radar-absorbing property.
