A terahertz metamaterial is a class of composite metamaterials designed to interact at terahertz (THz) frequencies. The terahertz frequency range used in materials research is usually defined as 0.1 to 10 THz. This bandwidth is also known as the terahertz gap because it is noticeably underutilized. This … See more Currently, a fundamental lack in naturally occurring materials that allow for the desired electromagnetic response has led to constructing new artificial composite materials, termed metamaterials. The metamaterials are … See more Development of metamaterials has traversed the electromagnetic spectrum up to terahertz and infrared frequencies, but does not yet include the visible light spectrum. This is … See more The first terahertz metamaterials able to achieve a desired magnetic response, which included negative values for permeability, were passive materials. Because of this, "tuning" was achieved by fabricating a new material, with slightly altered dimensions … See more By combining metamaterial elements – specifically, split ring resonators – with Microelectromechanical systems technology – has … See more Terahertz frequencies, or submillimeter wavelengths, which exist between microwave frequencies and infrared wavelengths can be metaphorically termed "unclaimed territory" where almost no devices exist. Because there are limits to propagating the … See more Generating THz electromagnetic radiation Without available terahertz sources, other applications are held back. In contrast, semiconductor devices have become integrated into everyday living. This means that commercial and scientific applications for generating the … See more Electromagnetic metamaterials show promise to fill the Terahertz gap (0.1 – 10 THz). The terahertz gap is caused by two general shortfalls. First, almost no naturally occurring … See more WebSep 23, 2024 · The subwavelength resonators in metamaterials can enhance the localized electric field, which can be utilized to resolve this difficulty. Here, a tunable terahertz (THz) metamaterial made from Tl 2 Ba 2 CaCu 2 O 8 (Tl-2212) HTS film is developed. The spectral response of Tl-2212 metamaterial has a tunable property at temperatures up to 90 K.
