Jerusalem Cross单元频率选择表面吸波特性的试验研究

Absorbing performances of Jerusalem Cross frequency selective surface

对传统的频率选择表面耶路撒冷十字单元进行优化,并研究单元形状、尺寸、介质层厚度以及金属贴片厚度对含FSS吸波体雷达吸波性能的影响。结果表明,通过设计适当的FSS单元形状,并调节单元尺寸以及贴片层和介质层的厚度,可以实现对吸波体共振频率和反射率值的调整,得到符合设计要求的吸波体。

The effects of the design parameters, such as unit shape, unit size, the thickness of dielectric layer on radar absorbing properties of the traditional Jerusalem Cross unit frequency selective surface （FSS） absorber were studied by experiments. The results indicate that the resonant frequencies and peak values of reflection loss can be optimized to accomplish the requirements of the designers by using proper design parameters of FSS.
