Scanning Beams by Multi Source Metasurfaces

The purpose of this paper is to present a very simple design strategy to obtain an easy switchable beam scanning capability from an individual modulated aperture based on metasurface technology at the Kuband regime. Such ability could be obtained even from passive metasurface (MTS) based devices and assumes nowadays a crucial importance in the development of advanced radio environments suited for advanced functionalities such as remote monitoring, detection and next gen cellular communications offered in a seamless way; besides, high-speed data streams should be offered to the growing number of end users to implement the mentioned functionalities (De Alwis, C., Kalla, A., Pham, Q. V., Kumar, P., Dev, K., Hwang, W. J., & Liyanage, M. “Survey on 6G frontiers: Trends, applications, requirements, technologies and future research,” IEEE Open Journal of the Communications Society, 2, 836–886, 2021.). These conflicting requirements can only be dealt with by mitigating the severe interference a traditional radio interface would experience, until new radio interface technologies can optimize the communications channel performance (Rappaport, T. S., Heath Jr, R. W., Daniels, R. C., & Murdock, J. N. “Millimeter wave wireless communications”. Pearson Education, 2015).
