FSS对TE极化波传输特性的实验研究

通过实验测试,从单元的尺寸、形状、介质加载以及各参数对入射角的敏感性等方面,初步探讨了频率选择表面(Frequency Selective Surfaces,简称FSS)对TE波的传输特性.结果表明,FSS的谐振频率主要由单元的尺寸和形状确定;介质加载使得FSS平板的谐振频率降低;加载不同厚度的介质对FSS的透波率和谐振频率影响不同;对称加载介质能提高FSS的传输特性对入射角的稳定性.

Experiment on Transmission Properties of TE-Polarized Plane Wave Incidented on Frequency Selective Surfaces

The transmission properties of TE-polarized plane wave incident on frequency selective surfaces(FSS) was preliminarily explored by experiment,especially in t he elementary geometry,types,the dielectric thickness,loading patterns,and t he sens itivities to the varying angles of incidence.The experimental results are descri bed as the following.The resonant frequency of FSS is mainly determined by the e lementary geometry and types.The resonant frequency of FSS decreases with the di ele ctric loading.The transmission ratio and resonant frequency are changed with the different dielectric thickness.The dielectric symmetrically loading can stabiliz e the FSS transmission characteristic as the angle of incidence is varied.
