In this paper, the design of a synthetical absorber with topology optimization resistance frequency selective surface and metal wires array structure is proposed. This design attempts to provide a broadband strong absorption over wide-angle incidence at microwave band, especially for TE-polarization wave. Commonly, thickness is positively correlated with the absorption performance, and the thin thickness with high absorption of the absorber is taken into adequate consideration in our work. As a result, the optimal structure designed by genetic algorithm achieves absorption over a wide frequency range of 8.2 to 19.5GHZ with reflection below 10dB and the broadband absorption is tolerant for the incident angle under 70 degrees (high absorption less than 60 degrees). The results of experiment and simulation are highly consistent. Whats more, the thickness of the resistive frequency selective surface and metal wires dielectric substrate are 2mm and 0.4mm respectively, enabling a wide range of applications in stealth technology, electromagnetic radiation protection, electromagnetic control and so on. |
