Active metamaterial array and method for manufacturing the same

A method for manufacturing an active metamaterial array, comprising:

• forming a plurality of metamaterial structures on a substrate to be spaced apart from each other;
• forming a semiconductor or a conductivity variable material layer between each of the plurality of metamaterial structures so as to selectively connect the metamaterial structures;
• forming an electrolyte material layer on the metamaterial structures and the conductivity variable material layer;
• and
• forming a gate electrode to be disposed at one end of the substrate so as to be in contact with one region of the electrolyte material layer,
• wherein 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,
• wherein as the conductivity of the conductivity variable material layer is changed, all of the plurality of metamaterial structures are connected or disconnected, and, thus, a resonant frequency and a phase are changed.
