Researchers propose a method to detect and map low-frequency excitations in nonlinear materials at nanometer resolution, enabling far-infrared fingerprints.

Computer-Controlled Sub-Aperture Polishing enables high-precision surface correction using small tools. Material removal is controlled by dwell time modulation along toolpaths, but the discontinuous ...

Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next-generation applications, including high-speed wireless communications, ...
