Large-element-spacing (LES) arrays provide cost-effectiveness and structural simplicity. However, they experience the drawback of excessive grating lobes. In this study, we tackle the problem by introducing a metasurface lens positioned above a non-uniform LES array. The purpose is to manipulate and...
