Emission is then obtained at the difference frequency of the lasers, and this can be engineered to fall in the terahertz range. Terahertz spectroscopy has some important differences when compared ...

To address this issue, we propose a simple approach to mitigate the feed blockage effect, thereby improving the gain to a certain extent. A modified FTA is proposed at a terahertz frequency band using ...

respectively, on the test data. The proposed work can pave the way for future research combining machine learning and sensing at the terahertz frequency.

By exciting a specific terahertz frequency vibrational mode, which displaces the crystal lattice along the coordinates of other modes in the material, we created a chiral state that survives for ...

By applying intense pulses of terahertz-frequency light to this material, they were able to control this transition, placing the material in a metastable magnetic state that lasts for more than 2.5 ...

Methods: In this study, qualitative and quantitative analysis of melatonin and 5-HTP was performed using Raman spectroscopy, powder X-ray diffraction (PXRD), and terahertz time-domain spectroscopy ...

Washing labels aren't always the most straightforward to read, and if you don't know what they mean you could end up ruining your clothes. Thankfully the symbols they use are (mostly) universal, so ...

Anybody can develop high frequency hearing loss, but it becomes more common with age. Exposure to loud sounds or high frequency sounds are common causes of ear damage in younger people.
