Abstract

A metallodielectric frequency selective surfaces (FSS) filter was optimized by a genetic algorithm (GA) to have dual stopbands in the mid-IR. Fabrication and measurement of this design demonstrated excellent filter properties with greater than 10 dB attenuation in the stopbands. However, blooming of the metallic patches resulted in a frequency shift in the measured response. Efforts are currently underway to improve the fabrication process so that the fabricated structures are faithful to the design parameters.
遗传设计的中红外多波段金属介电频率选择性表面滤波器
采用遗传算法对金属介电频率选择表面(FSS)滤波器进行了优化,使其在中红外波段具有双阻带。该设计的制作和测量证明了其出色的滤波性能,阻带衰减大于10 dB。然而,金属斑块的绽放导致了测量响应的频移。目前正在努力改进制造工艺,使制造结构忠实于设计参数。
