Alternative communications

Participant : Valeria Loscri.

In the last few years, there has been an increasing interest in the study of "alternative communication" paradigms, ranging from the exploitation of the visible light as carrier information, the exploitation of a different portion of the spectrum in the THz frequency, the leverage of artificial molecules for transmitting information (i.e. artificial molecular communication). Another interesting approach is consisting on a different perspective of the interaction between the signals and the environment. Right now, the environment has always been considered as something that cannot be "changed", a kind of obstacle for the wireless transmission. A new paradigm is arising, based on the metamaterial surface, where the interaction between the signals and the environment can be adapted in order to improve the performance of the communication.

TeraHez communications

In [32] and [23] we have investigated a metasurface and how the design of this metasurface has to be realized in order to adapt the behavior of the optical and THz signals based on the specific application considered.

Molecular communications

Concerning the artificial molecular communication paradigm, a fundamental aspect to be considered is that the most of times the target application of this type of communication is a biological system. A fundamental question arising is then: how maximize the effectiveness of the communication by keeping a low impact in terms of interference for the biological system? We have tried to answer to these fundamental questions by considering a signal processing approach in [11], [19].
