摘要

摘要: 根据国家军用标准GJB 150-86对不同涂层材料和加工工艺的频率选择表面(FSS,Frequency Selective Surfaces)进行了温度循环的环境模拟试验,通过比较温度循环前后FSS的谐振频率、传输损耗、频带宽度和入射角稳定性等传输特性的差异,考察FSS在温度循环条件下的性能稳定性.结果表明,温度循环对不同材料和工艺的FSS的传输性能有较大影响,主要表现在FSS的传输损耗和频带宽度两方面.不同FSS在经过温度循环后,谐振频率下的传输损耗增大0.5~3倍,入射角越大增大的幅度越大;频带宽度增加50%~70%,不同的FSS增加的幅度不同.而对谐振频率和入射角稳定性的影响根据不同的FSS而不同,但对二者的影响都不明显.与简单振子FSS相比,组合振子FSS的传输性能受温度循环的影响较大.

Abstract: Temperature shock test followed the criterion of GJB 150-86 was completed for frequency selective surfaces (FSS) of different coatings and different machining process. The stability of transmission properties of FSS under temperature shock test was studied by the difference before and after the test on resonant frequency, transmission loss, band width and sensitivities to the varying angles of incidence of FSS. The results are shown as follows. It has great influence of temperature shock test on the transmission properties of FSS, which mainly displays in two sides, transmission loss and band width. After the temperature shock test, transmission loss of FSS increases by 50%~300% for different coating and machining process FSS and the increase extent becomes greater with the increase of the incidence angle. The band width increases by 50%~70% for different FSS. The temperature shock has little effect on the resonant frequency and sensitivities to the varying angles of incidence and it has different influence for different FSS. In contrast with simple cell FSS, the transmission properties of compound cell FSS have more obviously change after temperature shock.
