A Tunable Microwave Absorber Based on Active Frequency Selective Surface

摘要：

　　A novel microwave absorber is presented in this paper.The absorber is a single layer structure based on the topology of a Salisbury screen,but in which the conventional resistive layer is replaced by an active frequency selective surface(AFSS)controlled by PIN diodes.The reflectivity response of the tunable microwave absorber can be controlling by adjusting the current in PIN diodes.Experimental results are presented and prove the working mechanism of the new absorber,which show that the reflectivity response can be modulated over the frequency band from 10 GHz to 12 GHz.
