Sushrut Karmarkar is a 5th-year PhD Candidate in the School of Aeronautics and Astronautics at Purdue University whose research focuses on structures and materials. Sushrut is originally from ...

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 ...

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 ...

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.

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 ...

The quest is on to make terahertz sources that are small, portable and capable of operating at room temperature. Such a breakthrough could lead to advances in everything from cancer screening to ...
