摘　　要：电磁屏蔽涂料的广泛应用要求有一种能快速有效确定屏蔽效能的测量方法。在介绍法兰同轴测试装置的基础上,提出了一种按远场同轴传输线测量平面材料的方法,用来测量屏蔽涂料的屏蔽效能。具体分析了测试系统的主要设备及其技术参数,同时给出了样本测试结果。结果表明,该测量方法能有效测试屏蔽涂料及类似平面屏蔽材料的屏蔽效能。It is necessary to find an effective and rapid measuring method to estimate the effectiveness for the application of electromagnetic shielding and coating materials becoming wider and wider. On the basis of introduction of the flange coaxial testing device, the measuring method based on planar material measurement with far-field coaxial transmission line is proposed. The main equipment and its technical parameters of the test system are introduced, and the test results on specimens are analyzed concretely. The results show that the shielding effectiveness of shielding coating materials and similar planar shielding materials can be effectively tested by the method with enhanced testing efficiency.
