[White Paper] Metamaterials and reconfigurable intelligent surfaces

[Roman99]

Vladan Jevremovic, "Metamaterials and reconfigurable intelligent surfaces"

Metamaterials are a new class of artificial materials, whose microstructure is engineered to exhibit unique electromagnetic properties not observed in nature, and previously believed to be physically inconceivable. All materials found in nature have periodic structure that consists of atoms. In metamaterials, an artificial periodic structure is created and inserted onto a host material. This artificial periodic structure has constituent elements that are larger than the host material atoms. This size difference has the effect of overriding the natural response of the underlying host material to the incoming electromagnetic wave. Thus, the resulting penetration and reflection loss as well as reflection angle are specific to the artificial structure and not to the underlying atomic structure of the host material. In this paper we talk about the key metamaterial features, introduce the concept of Reconfigurable Intelligent Surface (RIS) and describe the potential RIS use cases in modern wireless communications.
