Traditionally difficult to access, the terahertz (THz) region of the electromagnetic spectrum (0.1–10 THz), is higher in frequency than most electronic sources and lower in frequency than most optical ...
Optical imaging includes a variety of imaging techniques that rely on illumination light in the ultraviolet, visible and infrared regions of the electromagnetic spectrum. The term typically excludes ...
Abstract: This study investigates the integrity of lithium-ion batteries (LIBs) with the aid of guided ultrasonic waves (GUWs) generated by an active sensing network. Despite the expanding demands for ...
