Abstract: Low-sidelobe antenna arrays are widely used in the wireless systems for the anti-interference receiving. To achieve low sidelobe, the amplitudes of each array element follow a tapered ...

Abstract: Vortex electromagnetic waves carrying orbital angular momentum have been widely studied in many fields because of their unique helical phase structure. The vortex electromagnetic waves can ...
