从双层结构出发研究了一种由多块不同的单周期光子晶体组合而成的多层结构的滤波器 ,论述了这种滤波器的工作原理。研究表明这种结构适于制作带通、窄带通过、带阻、宽带带阻、高通以及其它各种性能的滤波器。实验和理论研究的结果相一致
Based on the double-layer structure, a multi-layer structure filter composed of many different single-period photonic crystals is studied. The working principle of this filter is discussed. Studies have shown that this structure is suitable for making passband, narrowband pass, bandstop, wideband bandstop, high pass, and other various performance filters. The experimental and theoretical findings are consistent
