| 摘 要： | 提出用吸波材料与金属材料双层复合代替单层金属材料对军用电子仪器进行屏蔽的设计.计算结果得出,这种复合材料的屏蔽效能在低频段与单层金属的屏蔽效能相当,但在高频段远远高于单层金属.另外,这种"内吸外反"的屏蔽材料,还有很好的吸收性能,特别是在高频段,大部分电磁波被其吸收,反射回来的电磁波很少,这样就为军用电子仪器防电磁泄漏和抗电子干扰提供可靠的保证.

| Abstract: | A design for screening military electronic machines using dual-layer composite of attenuating materials and metals instead of single metallic layer is proposed in this paper. The screening performance of this composite is much higher than that of single metallic layer in the high-frequency range,and is almost equivalent to that of single metallic layer in the low-frequency range. The inner-attenuating and outer-reflecting material has great attenuating ability to high-frequency waves. So the material can be used for military electronic machines to prevent electromagnetic leaking and electromagnetic jamming. |
