Terahertz Applications

This collection surveys the rapidly expanding landscape of terahertz (THz) science and engineering, with emphasis on application-driven advances. Spanning roughly 0.1–10 THz, this spectral region couples far-infrared photonics with high-frequency electronics and exposes unique material resonances, enabling capabilities that are difficult to realize at microwave or optical wavelengths. The articles gathered here trace a coherent arc from fundamental components and measurement methods to validated
