Tunable metasurfaces are ultra-thin, artificial electromagnetic (EM) components that provide engineered and adjustable functionalities up to the terahertz (THz) band and beyond. The concept of software-defined metamaterials (SDMs) has recently emerged as tunability has been applied at the unit cell level and exposed to the user via programmatic commands. To realize this approach, SDMs require the integration of a network of controllers within the structure of the metasurface, where each controller interacts locally and communicates globally to obtain the programmed behavior. At the same time, the approach allows to interconnect several metasurfaces to address complex EM problems in a distributed way. Within this networks inside networks context, the present chapter focuses on the communication requirements and implementation constraints of the controller network within the metasurface. Guidelines for the design of appropriate wired and wireless solutions are extracted from the analysis, paving the way to the realization of programmable THz metasurfaces.
