To evaluate the electromagnetic interference characteristics ofnext-generation aircrafts based on composite materials, the electromagnetic characteristicsof the these materials are measured and analyzed. First, the electromagnetic shieldingcharacteristics of various types of carbon fiber reinforced plastics (CFRP) are evaluated.The quasi-isotropic CFRP laminates have shielding effects around 50 dB, which is almostthe same as the aluminum plate. In addition, the electromagnetic field (EMF) characteristicsinside the CFRP structure made of woven fabrics were evaluated using thereverberation chamber. The measured quality factor confirmed no significant difference inthe aluminum and the CFRP sidewalls. Finally, based on the measured parameters, theEMF inside the aircraft cabin is analyzed using FDTD method.

为了评估下一代复合材料飞机的电磁干扰特性，对复合材料的电磁特性进行了测试和分析。首先，对不同类型碳纤维增强塑料（CFRP）的电磁屏蔽特性进行了评价。准各向同性CFRP层合板的屏蔽效果在50 dB左右，与铝板的屏蔽效果基本一致。此外，利用混响室对机织织物CFRP结构内部的电磁场特性进行了评价。测量的质量系数证实铝和CFRP侧壁没有显著差异。最后，根据实测参数，利用时域有限差分法对飞机舱内的电磁场进行了分析。
