标题： Simultaneous Angle-of-Arrival Sensing and Anomalous Deflection with Aperiodically Loaded Patch Arrays

摘要： 我们提出并数值演示了一种可重构的贴片天线阵列，该阵列能够在不事先了解传播环境的情况下同时实现入射波感知和异常反射。 我们通过准确且高效的感应负载电流优化以及改变无源负载的阻抗来抑制寄生散射，从而获得异常反射。 通过减轻寄生散射瓣，我们展示了通过优化负载电流分布的空间傅里叶变换准确检测入射照射角度的可行性，这由可调无源负载实现。 这种方法消除了对额外射频链、预计算数据或校准测量的需求。 所开发的策略将算术负载优化与到达角感知相结合，适用于一般的有限尺寸阵列。 显示英文摘要

摘要： We propose and numerically demonstrate a reconfigurable patch antenna array that enables simultaneous incident wave sensing and anomalous reflection without prior knowledge of the propagation environment. We acquire anomalous reflection by suppressing parasitic scattering through accurate and efficient optimization of induced load currents and by varying impedances of reactive loads. By mitigating parasitic scattering lobes, we demonstrate the feasibility of accurately detecting the incoming illumination angle via the spatial Fourier transform of the optimized load current distribution, facilitated by tunable reactive loads. This approach eliminates the need for additional RF chains, pre-computed data, or calibration measurements. The developed strategy, which integrates arithmetic load optimization with angle-of-arrival sensing, is applicable to general finite-size arrays.
