实验研究了多孔银膜在中红外波段的增强光学透射。具有经典电感频率选择表面结构的样品的光传输特性也受到周期性和孔径形状的影响。结果表明，等离子体激元晶体和频率选择表面的物理工作机制是相同的，并且由于周期性引起的表面等离子体激元和存在于单个空穴中的波导模式都对光传输增强有影响.
We experimentally studied the enhanced optical transmission of perforated silver films in the middle-infrared region. The optical transmission properties of the samples with classical inductive frequency selective surface structures are also affected by both the periodicity and the aperture shape. Our results indicate that the physical operating mechanisms are the same for the plasmon crystal and the frequency selective surface, and both surface plasmon polaritons due to the periodicity and waveguide modes that are present in single holes have effect in the optical transmission enhancement.
