"Until recently, the terahertz range was considered a blank area in the electromagnetic spectrum.... positioned between microwaves (used, for example, in Wi-Fi) and infrared .... it holds immense potential for applications that include inspecting packages without harmful X-rays, superspeed 6G communication, and spectroscopy and imaging of organic compounds..."
