The research in the N3Cat is currently focused in three main projects:
Graphene-enabled Wireless Communications
Graphene, in the form of graphene-based nano-antennas (or shortly named graphennas), is envisaged to revolutionize the realm of short-range wireless communications. The plasmonic effects occurring inside graphennas allow them to radiate electromagnetic waves in the terahertz band (0.1-10 THz), potentially enabling terabit per second transmissions. Moreover, at this particular frequency band, the size of graphennas is two orders of magnitude below that of metallic antennas. For all this, the current project will study the application of Graphene-enabled Wireless Communications (GWC) within the scenario of high-datarate off-chip and on-chip communication, in which the area occupied by the antenna and the transceiver might be a critical factor. The project is aimed at:
- The characterization of the electromagnetic properties of graphene-based nano-antennas
- The development of new channel models -including the antenna- for terahertz communications and distances below tens of millimeters
- The exploration of the coding and modulations design space for high-datarate communication, with particular focus on the impulse radio paradigm.

Fundamentals and Applications of Molecular Nanonetworks through Cell Signalling
The project on Molecular Communication focuses on the study and the analysis of information exchange through molecules. Molecular Communication research is carried out following a bio-inspired approach, thus envisioning a tight symbiosis between future synthetic devices and natural living organisms. Molecular Communication architectures can be found and studied in nature since they are at the basis of cell to cell information exchange. The main goal of the project is the design and the realization of communication architectures at the molecular scale, thus enabling a wide range of applications spanning from the biomedical to the environmental and military field. The project development includes: i) theoretical studies devoted to the understanding of the physics underlying information exchange through molecules; ii) mathematical modeling of the molecular communication channel using tools from Communication Engineering and Information Theory; iii) research of novel insights and breakthroughs enabling the design of communication systems for information exchange both among synthetic nano-devices and between synthetic nano-devices and living entities.
N3Sim: A Simulation Framework for Diffusion-based Molecular Communication
N3Sim is a complete simulation framework for diffusion-based molecular communications, which allows the evaluation of the communication performance of molecular networks with several transmitters and receivers in an infinite space with a given concentration of molecules. Transmitters encode the information by releasing particles into the medium, thus varying the concentration rate in their vicinity. The diffusion of particles through the medium is modeled as Brownian motion, taking into account particle inertia and collisions among particles. Finally, receivers decode the information by sensing the local concentration in their neighborhood. The benefits of such a simulator are multiple: the validation of existing channel models for molecular communications and the evaluation of novel modulation schemes are just two examples.
