ARCADIA will provide a reliable simulation tool to investigate thoroughly the expected performance of THz wireless communication systems, involving all the different stages of the communication, empowering the understanding of the capabilities and limitations of graphene technology with respect to the communication networks. The simulator will include channel models and the modeling of the HW impairments with a focus on graphene-based HW components. Therefore, specific objectives are:
Graphene-based robust components design and modelling of HW impairments;
Reconfigurable Intelligent Surfaces (RIS) for THz communications
Channel model development (focusing on non-time stationarity);
Waveform and PHY design;
Simulator of the physical layer of a THz link including baseband processing, channel models, HW impairments of graphene-based active and passive devices.

ARCADIA is part of Spoke 2 – Integration of Networks and Services

  • Reconfigurable Intelligent Surfaces (RIS) for THz communications Graphene based RiS enhance the functionality and performance of propagation channels, enabling advanced signal manipulation and control. In this context, a possible configuration of a graphene-based unit cell has been proposed, which will be the starting point for the design of a digital RIS. The definition of the model suitable for graphene conductivity in the THz spectrum has been performed and validated with the literature.
  • Channel models and standardization – Preliminary definition of the channel sounding setup; Initial contacts with the Channel Modeling and Standardization Group (CMSG) has been started. The CMSG started in 2021 as an ad hoc group in the standardization board of IEEE communication society and it is chaired by Andi Molisch and Naveed Abbasi. The CMSG aims to establish recommendations for channel parameters, models, and standards to address gaps in existing standardization.
  • Scientific A graphene-based unit cell suitable for the development of a reflective metasurface has been proposed and numerically analyzed. The design of the same was achieved by exploiting two different approaches: one digital and one analog. Through these approaches, several possible solutions were identified, which enable the realization of electromagnetic functions based on phase control of the reflected wave. These results have been presented at the European Wireless 2023 conference in Rome, Oct. 2-4. Future developments could involve the combination of the two approaches to achieve greater expressiveness in terms of the electromagnetic functions that the metasurface can exert. This device can pave the way for the realization of a new class of smart components for beyond 5G and 6G applications, as well as for 3D networks.
  • Industrial/Exploitable Numerical results are encouraging. Industrial interest and exploitation of research results could arise as a consequence of experimental demonstration of the designed devices. Although not planned in the project, during the development phase, an analysis can be done on the maturity of the technologies that could lead to an assessment of technology readiness level (TRL). If it proves to be high enough, this prototype can be of wide interest for industry.
During the European Wireless conference 2023, hold on the 2-4 Oct. in Rome, Ilaria Marasco (Politecnico di Bari) presented the paper: “Design of a Graphene-Based Reconfigurable Intelligent Surface in THz Spectrum” Authored by: Ilaria Marasco, Giovanni Magno, Ernestina Cianca, Antonella D’Orazio, Marco Grande. The paper have deeply analyzed graphene-based modulators, phase shifters and antennas with a particular focus on RIS. Moreover, a graphene-based unit cell suitable for the development of a reflective metasurface was proposed and numerically analyzed. The design of the same was achieved by exploiting two different approaches: one digital and one analog. Through these approaches, several possible solutions were identified, which enable the realization of electromagnetic functions based on phase control of the reflected wave. Future developments could involve the combination of the two approaches to achieve greater expressiveness in terms of the electromagnetic functions that the metasurface can exert. This device can pave the way for the realization of a new class of smart components for beyond 5G and 6G applications, as well as for 3D networks.

Collaboration proposals
ARCADIA looks for collaborations in the activity related to the development of graphene-based antennas and metasurfaces in the range between 100-300 GHz or beyond, focused on the numerical design and assessment of their feasibility. Whether an experimental prototype is required, it will be necessary to establish a collaboration with other research groups for the fabrication of graphene-based devices. Moreover, it will be also necessary to establish a collaboration with research groups able to characterize these devices in the frequency range of interest.
