Abstract
A recently proposed class of materials, called software-defined
metamaterials, can change their electromagnetic behavior on demand, utilizing a
nanonetwork embedded in their structure. The present work focuses on 2D
metamaterials, known as metasurfaces, and their electromagnetically
programmable counterparts, the HyperSurfaces. The particular focus of the study
is to propose a nanonetworking protocol that can support the intended
macroscopic functionality of a HyperSurface, such as sensing and reacting to
impinging waves in a customizable manner. The novel protocol is derived
analytically, using the Lyapunov drift minimization approach, taking into
account nano-node energy, communication latency and complexity concerns. The
proposed scheme is evaluated via simulations, covering both the macroscopic
HyperSurface functionality and the microscopic, nanonetwork behavior.
