WebThe terahertz (THz) region of the electromagnetic spectrum is generally defined as the frequency range of 0.1–10 THz (10 12 cycles per second) corresponding to quantum energy of 0.4 meV–0.4 eV (see Fig. 1 ). THz electromagnetic waves (also known as T-rays) have several properties that could promote their use as sensing and imaging tool. WebThe ability of terahertz waves to pass through solid objects and other materials without destructing them has created interest in the scientific world and more research has been put into Terahertz wave technology, resulting in many new devices in the fields of imaging, spectroscopy, scanning, besides medical, biological, and therapeutic use.
