Full‐Space Near‐ and Far‐Field Jones Vector Reconstruction by Global Organization of Bidirectional Non‐Interleaved Linear‐Polarized Meta‐Radiators

Abstract

AbstractIntegrated radiation‐type metasurfaces (RA‐M) have gained importance in the development of next‐generation wireless communications and integrated electronics. They facilitate advanced electromagnetic (EM) wave control with a single radiation aperture. However, most RA‐Ms fail to simultaneously decouple the amplitude, phase, and polarization information of the spatial radiation wavefront owing to the intrinsic restrictions of the meta‐radiator and limited design strategy. This study proposes and demonstrates a full‐space non‐interleaved RA‐M platform capable of precise complex‐vector‐field (CVF) Jones vector reconstruction of both near and far fields in the microwave region. The method is based on the global interaction of linear‐polarized (LP) meta‐radiators, which are organized via the LP‐basis inverse design methodology; thus, the near‐ and far‐field Jones vectors of the radiated wavefront can be subjected to customized reconstruction. The existing unidirectional meta‐radiators are further pushed to bidirectional spaces, facilitating diverse full‐space multiplexing integrated meta‐devices, such as bidirectional multi‐polarization routers and full‐space vectorial hologram modulators. The proposed RA‐M unlocks the unequaled potential of radiated CVF, thereby paving a promising pathway for integrated electronic device technologies.
