实验研究了正方形金属贴片阵列及其互补结构方孔阵列的微波响应。共振现象，产生增强的透射或反射，归因于衍射耦合表面波的激发。这些表面模式的能带结构已被量化为p-（横向磁）和s-（横向电）极化辐射，并被发现是依赖于共振的电场和磁场的周期性。计算结果与有限元法模拟的结果和巴比涅原理的电磁形式[Babinet，C。R. Acad. Sci. 4，638（1837）]。
The microwave response of an array of square metal patches and its complementary structure, an array of square holes, has been experimentally studied. The resonant phenomena, which yield either enhanced transmission or reflection, are attributed to the excitation of diffractively coupled surface waves. The band structure of these surface modes has been quantified for both p-(transverse magnetic) and s-(transverse electric) polarized radiation and is found to be dependent on the periodicity of the electric and magnetic fields on resonance. The results are in excellent accord with predictions from finite element method modeling and the electromagnetic form of Babinet’s principle [Babinet, C. R. Acad. Sci. 4, 638 (1837)].
