This research presents the design and simulation of an optically transparent metamaterial absorber using an intelligent pattern design method. The proposed absorber consists of a 4 mm thick polycarbonate substrate with a continuous ground plane made of a transparent conductive material such as ITO with a surface resistance of 20 Ω/sq placed beneath it. A metamaterial pattern of the same material as the ground plane is placed on top of it. To improve impedance matching over a ultra-wide bandwidth and protect the metamaterial pattern, a polycarbonate layer is placed on top of the metamaterial pattern. For the design of the metamaterial pattern, an intelligent method based on the binary particle swarm optimization (BPSO) algorithm [2] is used, which leads to a reduction in design time and improvement in the structure's performance. The proposed absorber provides more than 90% absorption in a wide bandwidth of 3.8-18.85 GHz, which completely covers all the target frequency bands of this research, namely C, X, and Ku.
