Abstract: An active metamaterial array of the present disclosure includes: a substrate; a plurality of metamaterial structures disposed on the substrate and spaced apart from each other; a conductivity variable material layer formed between each of the plurality of the metamaterial structures so as to selectively connect the metamaterial structures; an electrolyte material layer formed on the metamaterial structures and the conductivity variable material layer; and a gate electrode disposed at one end of the substrate so as to be in contact with one region of the electrolyte material layer, and when an external voltage is applied to the gate electrode, the gate electrode changes the conductivity of the conductivity variable material layer by controlling the migration of ions contained in the electrolyte material layer.
