摘要：
Proposed in this paper is a conductive film metamaterial absorber that capitalizes on the impedance matching principle, offering ultra-wideband microwave absorption alongside high flexibility and transparency. Simulation results indicate that absorptivity surpassing 90% within the 0.85GHz to 25 GHz frequency range, with a remarkable 186.8% relative absorption bandwidth. Furthermore, the absorber exhibits polarization-insensitive characteristics and sustains effective absorption for electromagnetic waves at incident angles below 60 degrees.
