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 ...

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.
