摘　　要：频率选择表面(FSS)可实现对特定频率电磁波的选择性透过或反射。为适应武器装备表面及电磁环境的日益复杂化,需要开发可重构的柔性化FSS,以实现谐振频率的可调节、可开关及与复杂曲面的共形。本文分析了FSS重构的基本原理,综述了现有可重构FSS的制备手段,包括通过加入集总二极管、改变周期单元结构和尺寸及材料电磁参数等。结合现有柔性纺织基FSS的多尺度结构及灵活多变的织造技术,指出依托纺织加工手段制备的频率选择织物可兼具易共形、可重构和机械强力,并具有多尺度的灵活可调特征,是柔性基FSS的未来发展方向。Electromagnetic wave can be transmitted or reflected by frequency selective surface(FSS)at the resonant frequency.To adapt to the increasing complexity of the weapons'surface and the electromagnetic environment,it is necessary to develop a reconfigurable flexible FSS,which can make the resonant frequency adjustable,switchable and conformal with complex curves.This paper analyzes the basic principles of reconfigurable FSS,and summarizes the available preparation methods of reconfigurable FSS,including adding lumped diodes,changing the size and space of the conductive periodic unit,and changing electromagnetic parameters,etc.It is concluded in our discussion that,owing to the existing multi-scale structure of variable textile-based FSS and the flexible weaving technology,frequency-selective fabrics prepared by textile processing methods can realize conformality,reconfigurability,mechanical strength,and multi-scale and flexible adjustability,thus representing the future trend of flexible-based FSS.
