“…Plasmonic reconfigurable intelligent surfaces [215,216], on the other hand, have potential applications in the development of revolutionary wireless technologies for beam bending at THz frequencies [217]. We also envisage the application of the Pancharatnam-Berry geometric phase, recently used for integrated millimeter-wave broadband CPL single-beam/multibeam antennas [218], for the development of analogous platforms at nanoscale dimensions [219,220]. Other concepts like MO and magnetoplasmonic effects are expected [221][222][223][224][225].…”

Plasmonic materials, when properly illuminated with visible or near-infrared wavelengths, exhibit unique and interesting features that can be exploited for tailoring and tuning the light radiation and propagation properties at nanoscale dimensions. A variety of plasmonic heterostructures have been demonstrated for optical-signal filtering, transmission, detection, transportation, and modulation. In this review, state-of-the-art plasmonic structures used for telecommunications applications are summarized. In doing so, we discuss their distinctive roles on multiple approaches including beam steering, guiding, filtering, modulation, switching, and detection, which are all of prime importance for the development of the sixth generation (6G) cellular networks.

“…Other techniques for achieving multibeam antennas using passive structures have also been considered. These include the circuit-based Butler matrix beamformer [82] and quasioptical architectures using multi-feed lenses [83], [84]. Although the generated beams are static with each beam pointing in a pre-defined direction, these antennas are low-cost and light-weight and are useful in certain application scenarios.…”

“…Regarding the beam coverage, even though a wide range of 82° is achieved in [29], the aperture efficiency is low and scanning loss is large. The designs from [22] and [30] provide very low scanning losses, but the scanning ranges are limited. It is noticeable that our array has a greater beam scanning range and a small scanning loss without sacrificing the aperture efficiency.…”

“…One popular technology is to utilize the bifocal phase compensation method initially presented in reflectarrays [21]. In [22], circularly-polarized multibeam transmitarrays are developed at 26 GHz, generating five pencil beams that cover a range of ±33° with a scanning loss of 1.2 dB. The peak boresight gain is 22.2 dBic.…”

A transmitarray antenna with an elliptical cylindrical shape is presented for a wide-angle multibeam radiation in this paper. The transmitarray has a cylindrical radiating aperture with an elliptical cross section, namely, elliptical cylindrical shape. Multiple feeds can be placed on the middle horizontal plane to realize multiple beams. Inspired by a twodimensional (2-D) Ruze lens, the antenna shape and the phase compensation are jointly designed according to the desired maximal beam direction. Innovative methods including a feed refocusing analysis and a virtual focal length are utilized to achieve the phase compensation across the threedimensional (3-D) aperture for multiple beam radiations with a small scanning loss. In order to validate the proposed antenna, a prototype operating in the millimeter-wave band has been designed, fabricated and measured. By changing the position of the feeding gain horn along the refocusing arc, the main beam of antenna can be scanned to eleven directions. The measured peak boresight realized gain is 27 dBi at 70.5 GHz and a beam coverage of ±43° with a less than 2.7-dB scanning loss is obtained.
