Trend of Terahertz in Metamaterials
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
Interest in engendering, identifying and deploying terahertz (THz) waves by using either photonic or electronic properties of the material in THz frequencies is still challenging part, where the metamaterials open a path to bridge the socalled “THz gap”. Terahertz radiation (T- rays) will provide opportunities on the growth of metamaterials which have the enormous electromagnetic properties present in it. With the concept of negative permittivity and permeability find a new artificial material named metamaterials has all the properties which are not available in nature started finding out a wide range of the structures in all the dimensions reviewed in terms of their concepts, an area of use and its applications. Terahertz metamaterials in the field of science and technology would provide excellent growth which leads to advance the research by controlling the electromagnetic fields desired for the implementation and fabrication. This paper recalls the properties of metamaterials and provides a wide view for their demonstrated applications and takes it to the next generation of Terahertz frequencies & devices. The review includes the various structures of metamaterials used in terahertz domain and the power sources used which are beyond the infrared and microwave region.
