Terahertz technology is the research field dedicated to the generation, detection, manipulation, and application of electromagnetic radiation within the terahertz (THz) frequency spectrum (typically 0.1–10 THz). This domain investigates the unique interactions of THz waves with matter, exploiting their non-ionizing nature and penetrative capabilities for advancements in areas such as spectroscopic material characterization, high-resolution imaging, and advanced communication systems.
