Computational Microwave Imaging Relying on Orbital Angular Momentum Transmitarrays for Improved Diversity
Miguel Angel Balmaseda-Marquez, Guillermo Ãlvarez-Narciandi, MarÃa GarcÃa-Fernández +3
This work proposes the use of orbital angular momentum (OAM) waves to improve the performance of a computational imaging (CI) system. Specifically, in contrast to a solely frequenc…
