摘要
This work proposes a synthetic design for a microwave absorber and antireflection to achieve reduction of wideband scattering. Simultaneous control of the absorption and scattering pattern of metasurfaces can be achieved by theoretical analysis and calculation aimed at improving the reduction of backward reflection. With a topologically optimized design and antenna array synthesis, customized absorption and an optimal arrangement can be achieved over a broad spectrum within an integrative optimization procedure. To validate the design method, a wideband low radar cross-section metasurface is proposed, for which good agreement is observed between simulations and experiment with pronounced reflection suppression from 9 to 23.9 GHz. This work reveals the opportunity for use of a metasurface in effective manipulation of microwaves and a synthesis optimization method for designing a high-performance flexible low-scattering platform.
