Market Definition
Terahertz (THz) is a unit of measuring frequency equal to 1 trillion hertz (10¹² Hz). It usually refers to the frequency of an electromagnetic wave, which is a part of the electromagnetic spectrum invisible to the naked eye and lies between the microwave and the infrared ranges. T-rays are an example of a specific part of the spectrum within the ITU-designated band, ranging from 0.3 THz to 3 THz, and are widely used in astronomy. These waves can pass through a variety of amorphous substances, including several synthetics and textiles. Paper and cardboard are also transparent to terahertz waves. The penetration of conventionally opaque materials and high chemical selectivity are the two main advantages of terahertz radiation; thus, it has a wide range of applications. Major types of terahertz technology systems available in the market include terahertz imaging, terahertz spectroscopy, and terahertz communication systems.
