Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next ...

WASHINGTON — Researchers have developed a neural network model that uses terahertz time-domain spectroscopy (THz-TDS) data for non-invasive burn assessment. They combined the new approach with a ...

A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses terahertz wavelengths to probe samples, physicists at RIKEN University, Wakō, Japan, have ...

Because the signal in terahertz time-domain spectroscopy is weak, most experimental setups add external modulation to the signal for lock-in detection. This allows the signal to be easily ...

Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...

Conventionally, active metasurface scientists have mainly concentrated on altering the dielectric constant and permeability of the substrate, which usually leads to resonance effect and ohmic loss.
