Abstract

We fabricated an electrically tunable metamaterial based on twisted nematics liquid crystal cell, where polarization dependent reflectance of the metamaterial can be controlled via applied voltage. When the metamaterial-twisted nematics liquid crystal cell is driven with a voltage above the threshold, optical reflection of the cell has changed. Our result provides the possibility of tuning the frequency selective properties of metamaterials by applied voltage.
