Tunable terahertz and optical metamaterials

Abstract

This paper reviews recent developments of tunable THz and optical metamaterials and gives insights into the trend of future research in this field as well as the potential applications. It can be expected that tunable metamaterials will remain to be a hot topic in metamaterials and their developments may lead to a revolution in optical devices and systems and make a deep impact on the development of photonic and THz technology.
