Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...
Abstract: Sixth-generation (6G) wireless communication systems impose stringent requirements on antenna performance, including ultra-high data rates, ultra-lowlatency, massive connectivity, ...
Abstract: This paper presents a highly integrated and power-efficient millimeter-wave (mm-wave) antenna array system that enables two-dimensional (2D) controllable beamwidth using a novel polarization ...
