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

• Optimized design of graphene-based devices operating in the range of TeraHertz. In particular, a graphene based reconfigurable intelligent surface working as reflector has been designed. Moreover, the following graphene - based antennas have been designed: a circular disc-shaped transparent antenna which exploits graphene twin sector parasite to obtain beam steering in sub-THz range has been designed; an antenna consisting of two orthogonal dipoles surrounded by eight fan-blade shaped graphene parasitic sectors.
• Channel Sounding and Modeling – ARCADIA is working on setting up a channel sounding campaign. In the meantime, we have used Angle-of-Arrival (AoA) measurements available in the existing open literature to characterize the angular dispersion and Second-Order Fading Statistics for sub-THz communication channels in several representative environments at frequencies ranging from 125 to 300 GHz.
• Waveform Design – Setting up a baseband simulator to investigate the performance of Orthogonal Time Frequency Space (OTFS) waveform at THz in presence of Phase Noise (PN).

Reconfigurable Intelligent Surfaces (RIS) for THz communications - So far, by harnessing the unique properties of graphene and periodic structures, ARCADIA has developed a novel transparent reflective intelligent surface (RIS) with digital programmability. This metasurface can operate as both modulator and reflector, enabling dynamic electromagnetic wave manipulation via reflected wave phase control, paving the way for the realization of a new class of smart components for beyond 5G and 6G communication systems.

Graphene-based components for THz/sub-THz communication systems are not a consolidated reality.
ARCADIA project is one of the first project aiming to provide insights on the feasibility and limits of such technology for THz communication. Moreover, the channel sounding campaign focused on non-stationary channels, and the developed channel models will provide fundamental inputs to the design of communication and sensing systems at THz (not necessarily at graphene). ARCADIA is currently actively involved in a initiative aimed to develop a competence center for: Technology Scouting, Design, Implementation, Test of state of the art HW for mmw/THz telecom apps.
We think that participating in this initiatives will help in increasing the impact of the ARCADIA project results in the long term and will further stimulate synergies with other RESTART/non RESTART projects.

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.
For any proposal of collaboration within the project please contact the project PI.
