- Bistatic RCS Pattern Synthesis With a Receiver–Transmitter Metasurface and a Phase Distribution Optimization Algorithm Boyu Sima Yibang Xu Huangyan Li Xiang Wang Zhiyuan Zong Wei Kang Wen Wu Microwave and Optical Technology Letters ABSTRACTThis paper proposes a metasurface design method to achieve bistatic radar cross‐section (RCS) pattern synthesis in space, based on a receiver–transmitter metasurface (RTMS) and a genetic algorithm for phase distribution optimization. Due to the slots on the ground between the adjacent metasurface elements, the unwanted interunit coupling effect is significantly reduced. Based on the theoretical analysis model of the phased array, the corresponding phase distribution of the required RCS pattern is optimized by a genetic algorithm. According to the required phase distribution, the corresponding RTMS units are designed, and the overall RTMS structure is finally constructed. The simulated results demonstrate that the electromagnetic (EM) waves scattered by the proposed RTMS are concentrated in the desired directions of 0° and ±49° which is consistent with the design intention. Both simulated and measured results verify that the proposed RTMS design methodology can realize the bistatic RCS control in space with a customized shape. 10.1002/mop.70028 http://onlinelibrary.wiley.com/termsAndConditions#vor
