Evaluation of Channel Capacity of a 3D Curvilinear Metasurface in the THz band
Résumé
Metasurface structures (MSs) are able to control an impinging electromagnetic wave, in terms of amplitude and phase. Based on the prominent results of a specific curvilinear MS [1], designed and described by its equivalent nonhomogeneous Transmission Line (TL) model, in this paper we are motivated to investigate the achievable channel capacity bounds of the structure in the THz band. Through its equivalent circuit model, we are able to derive the attenuation behavior of the proposed MS, which is dependent not only on the geometric features of the MS, but also on its TL components. We observe a MS geometry-and frequencydependence, which reflect also on the channel capacity upper bounds. Specifically, by varying the input power profile of an impinging electromagnetic wave, we can achieve different trends of the channel capacity. Best performance are reached assuming input femtosecond Gaussian-shaped power pulses, that allow to achieve Pbps channel capacity upper bounds.
