Abstract
This article discusses fundamental properties of metamaterials. Firstly, it is argued that the defining property of metamaterials is emergence and not that they should display properties not observable in nature. In addition, the regime where matter can be assigned effective properties will be quantified using concepts of metamaterialization period and number of generations.
