Filling the terahertz gap
WebDespite Vietnam’s progress in providing a spectrum of support to persons with disabilities (PWDs), a noticeable gap still remains in the availability of interdisciplinary rehabilitation services. To address this, USAID’s Hold My Hand project, implemented by the Institute of Population, Health and Development (a Vietnamese non-profit organization), aims to … WebIn engineering, the terahertz gap is a frequency band in the THz region for which practical technologies for generating and detecting the radiation do not exist. It is defined as 0.1 to 10 THz ( wavelengths of 3 mm to 30 µm) although the upper boundary is somewhat arbitrary and is considered by some sources as 30 THz (a wavelength of 10 µm). [26]

WebThis is called Terahertz gap. In other words, Terahertz gap is the frequency range from 0.3 to 30 THz of EM spectrum as shown in the figure. The terahertz frequencies find applications in spectroscopy, pulsed imaging, impulse ranging, communication, sensing, security, mine detection, bio-chemical agent detection and so on. WebDynamically tunable terahertz metamaterial absorbers integrating with active materials have been widely explored. However, there are still problems that need to be urgently solved, such as modulation depth deficiency, a lack of multiparameter-tunable characteristics, and so on. In this paper, a multiparameter-tunable terahertz absorber composed of two …

WebHowever, applications for the terahertz regime, previously defined as the terahertz gap of 0.1 to 10 THz, is an impoverished regime by comparison. Sources for generating the required THz frequencies (or wavelength) exist, but other challenges hinder their usefulness. WebMar 14, 2024 · A new generation of technology is now possible thanks to a revolutionary device made from graphene. In a newly published paper, researchers claim they have built an amplifier that unlocks the frequencies between infrared light and microwaves, a previously unused bandwidth known as the terahertz gap.
