We review recent research on metamaterial-based devices for the terahertz frequency range. Possible applications for terahertz metamaterials include high-speed modulators, highly sensitive devices for refractometry or thin film sensing, efficient polarization optics, terahertz-absorbing materials, and high-performance gradient index optics. Due to the high flexibility in metamaterial design, these devices have the potential to outperform existing devices based on conventional materials.
