Beam‐Reconfigurable Retrodirective Array

A conceptual illustration of a beam-reconfigurable retrodirective array composed of dual-beam radiating elements with a tunable metallic plate, which can reflect an incident wave back along its incident direction while simultaneously generating a steerable secondary beam. This beam reconfiguration capability enables the array to be suitable for multipoint communication and wireless power transfer in moving scenarios. More details can be found in the Research Article by Yan Shi and co-workers (DOI: 10.1002/nap2.70240).
