Fifth-generation (and beyond) networks are characterized by ever more demanding requirements in terms of speed, bandwidth, and number of servable users.Fast and reliable access to the main network is mandatory, requiring technologies and procedures that ensure high performing cell search and initial access (IA).Existing phased array antennas (PAAs) are limited by hiboost 4k smart link the single beam scanning approach and complex feeding systems.In this paper, a beamforming metasurface that shifts the field manipulation from an electric level to an electromagnetic one is proposed for speeding up the IA procedure with respect to a traditional system using PAAs.The main advantage is given by the simultaneous transmission of multiple signals in different directions.

The numerical results demonstrate that a much abc material faster IA with similar success probability can be reached.Our system provides high gain, parallel computation, and scalability for larger systems, becoming a relevant candidate in the new radio and smart electromagnetic environment context.
