| 摘 要： | 电磁屏蔽建筑材料在当今信息化社会中具有重要的应用价值。在水泥砂浆中添加金属螺旋圈材料,在10kHz～1500MHz范围内进行电磁屏蔽性能测试。结果显示,随着频率的增加,屏蔽性能一般逐渐增强,在550MHz、1050MHz附近都有2个明显的拐点;在10kHz～550MHz范围,屏蔽效能都小于4dB;但在900～1050MHz频率范围内,最大屏蔽效能都能够超过10dB。 |

| Abstract: | Building materials for electromagnetic shielding have extensive application in electronic information society.Steel spiral circle were added in mortar,shielding effectiveness of mortars were studied with the coaxial cable measurement in 10kHz~1500MHz.The results show that with the increase of frequency,shielding effectiveness increases gradually and the effectiveness curves have 2 manifest inflection points nearby 550MHz and 1050MHz.During 10kHz~550MHz,shielding effectiveness were less 4dB,but during 900~1050MHz,shielding effectiveness can exceed 10dB. |
| Keywords: | steel spiral circle mortar electromagnetic shielding |
