研究了含Minkowski活性碳毡电路屏复合材料的微波吸收特性,并对电路屏的吸波机理进行了初步的探讨.结果表明,含Minkowski活性碳毡电路屏复合材料的吸波性能与电路屏阵列单元的尺寸密切相关,经合理设计,复合材料在5.3～18GHz频率范围内有-10dB以下的吸收,有效带宽达12.7GHz.复合材料对电磁波的主要吸收机制是电磁波在电路屏和反射板之间的多次反射、衰减.
Microwave absorbing properties of composites containing Minkowski ACF FSSs are investigated, and the absorbing mechanism of Minkowski FSSs is briefly discussed. Results show that the absorbing performances of composites are affected greatly by the element configurations of the screens. If properly designed, the composite containing the Minkowski screen can show a reflection loss blow -10dB in the frequency region 5.3-18GHz. The main attenuating mechanism of composites is EMW multiple reflection and attenuation between the screen and reflector plate.
