The microwave behaviour of a frequency selective window consisting of a cascade of two optically transparent band-stop frequency selective surfaces (FSSs) made with highly conductive, highly transparent thin-film indium tin oxide (ITO) is investigated. The performance of the ITO FSS structure is compared to a similar structure made from copper. Experimental results demonstrate the improved band-stop behaviour of a double layer window over a single layer one.
