In the last decades, Terahertz science and technology has progressed at a fast pace because of its many potential applications. The absence of suitable devices to operate in this region, created many obstacles to fully use this region of the electromagnetic spectrum. Metamaterial has become one of the most promising remedies to overcome this problem in the last decade. The scaling property of metamaterial made it the most suitable candidate for creating active materials in the terahertz regime. Liquid crystal based metamaterials provide the opportunity to tailor the properties of metamaterials after they are fabricated. One potential way to tailor the properties of metamaterials is to thermally tune them, providing potential applications as switches and filters. Liquid crystal is a well known bi-refringent material whose refractive index can be changed dynamically. The use of liquid crystal in the superstrate layer of the metamaterial gives the freedom to change the resonant frequency of the metamaterial. In this thesis electric split ring resonators are designed to work in the terahertz region and the prospect of tuning its properties with liquid crystal is studied The theoretical results show potential applications as tunable filter and switch. The device is fabricated and measured in a standard set up whose results are in agreement with the theoretical result.
