| Abstract: | Active frequency selective surface(AFSS) is a novel kind of frequency selective surface(FSS) fabricated by adding a series of impedance components among the unit cells of traditional FSS.The electromagnetic characteristics of AFSS are adjustable.The adjusting mechanisms of the electromagnetic characteristics of AFSS are analyzed first,and then the research progress and prospects of AFSS for the tunable electromagnetic shielding architectures,tunable spatial electromagnetic filters,tunable radars and antennas as well as the smart absorbing structures are introduced,with emphasis on the application of AFSS in the smart absorbing structures.Finally,several analysis methods for AFSS are reviewed. |
