A novel frequency-selective surface-enhanced composite honeycomb absorber with excellent microwave absorption

HIGHLIGHTS

• What: The authors designed, fabricated, and tested the performance of an FSS-enhanced composite honeycomb absorber (FSS-CHA). In this paper, a control-variable approach is used in the optimization process, in which some parameters are determined first, and then subsequent parameters are determined according to these parameters to improve computational efficiency. The authors determine p in CHA when h and d is 9 mm and 1 mm, respectively.
