摘要：
A light-weight and wideband X-band absorber employing a resistive silver nanowire (AgNW) film is presented. One unit of the absorber is composed of a cross-shaped AgNW resistive film and a conducting plane separated by a 7.5 mm (lambda(0)/4 at 10 GHz) Styrofoam (epsilon(r) = 1.03) layer. The used surface resistance of the film is 42 Omega per square. The 90% absorption bandwidth of the absorber is 80% from 6 to 14 GHz with a near complete absorption at the centre frequency of 10 GHz. Besides, it is also shown to be polarisation-insensitive.
