对频率选择表面的元件进行卷积产生具有非常小的单位单元尺寸的谐振结构。当FSS用于低频、安装在曲面上或放置在紧凑型辐射器附近时，此功能很有吸引力。分析和测量了单、双偏振卷积频率选择表面的特性。发展的新的卷积元素来自方环槽跟踪和他们的性能进行检查。一种新的交织卷积环的技术允许进一步减小单元尺寸，同时增加通带宽度，在宽带FSS设计中引入灵活性，特别是用于定制建筑物的电磁架构，以及建筑环境中的移动的通信。卷积结构的透射响应的模拟结果与测量结果吻合较好。
Convoluting the elements of frequency selective surfaces produces resonating structures with very small unit cell dimensions. This feature is attractive when the FSS is to be used at low frequencies, mounted on a curved surface, or when placed in the proximity of compact radiators. The characteristics of single and dual polarized convoluted FSS are analyzed and measured. The development of novel convoluted elements derived from the square loop slot is traced and their performance is examined. A novel technique of interweaving convoluted loops allows for further cell size reduction, while increasing the passband width, introducing flexibility in wideband FSS design, particularly for tailoring the electromagnetic architecture of buildings, and mobile communications in the built environment. Simulated transmission responses of the convoluted structures are in good agreement with the measurements.
