Abstract
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.
