Abstract: Analytical expression of transmission for the orbital angular momentum (OAM) communication using loop antenna arrays and paraboloids is derived to achieve a communication distance of 100 m.
Abstract: Superdirectivity enables compact arrays to achieve high directivity, but its practical implementations are highly sensitive to physical imperfections. This lack of robustness hinders the ...
