The Market for Terahertz is forecast to reach $1,382.66 million by 2025, growing at a CAGR of 27.44% from 2020 to 2025. Terahertz (THz) represents the portion of the electromagnetic radiation between the microwave and the infrared region. It is within the frequency range of 0.1–10 THz, corresponding to wavelengths of radiation from 3000 to 30 µm. This technology is poised to be fast growing in the coming years owing to its properties such as high chemical sensitivity and non-ionizing property.
Americas is set to be the dominant region for Terahertz market owing to the high adoption of terahertz technology in defence sector.
Industrial NDT is analysed to be dominant segment in the terahertz market owing to the wide spread applications of terahertz technology in the non-destructive testing equipment.
Increasing demand from the security is analysed to be the key driver for the terahertz market.
Sensor Type – Segment Analysis
Micro Bolometer is analysed to grow at highest rate during the forecast period. Micro bolometers are used as detector in thermal cameras. Micro bolometers detects the terahertz radiation and changes the electrical resistance. The development of terahertz imaging systems based on narrow band micro bolometers sensors and novel diffractive lens are successfully applied for spectroscopic microscopy applications. The narrow band micro bolometer sensors (NBMS) is a sensitive terahertz frequency selective sensor which is widely used nowadays for the development of compact all electronic systems for multispectral terahertz measurements. The terahertz using micro bolometers for sensing applications are the most suitable detectors for terahertz imaging and spectroscopic applications.
Application- Segment Analysis
Industrial NDT segment is the major segment by application for the Terahertz market. This is owing to the properties that this technology has that improve various industrial operations. Terahertz imaging is widely used in aircraft, spacecraft non-destructive testing applications. In aircrafts, exterior is coated with specialty chemicals that are particularly difficult to measure. Terahertz pulses can be used to measure coating thickness once the coating gets dried. Adoption of portable terahertz scanners in aircrafts in providing the necessary information to assemble the airframe in order to ensure that parts are properly aligned is set to drive the terahertz market. In 2019, Teratonics, a French based deep tech start-up with a proprietary technology for contactless non-destructive testing (NDT) and imaging had received a seed investment from Socomore Ventures. Growing funding activities for terahertz systems in NDT applications is set to provide opportunities for the market.
Geography – Segment Analysis
Americas dominated the terahertz market in 2019 majorly attributed to the Adoption of this technology, in initial stages. Also, there is high production and export of terahertz devices from this region for defence sector, further contributing to its dominance. However, Asia-Pacific region is estimated to be the fastest growing region and will witness a CAGR of 30.34% during the forecast period 2020-2025. Large amount of investments as well as the research are being performed in these countries are resulting in the rapid growth of terahertz technology in this region for the coming years. Due to the large presence of manufacturing companies in China, a moderate growth rate is expected in the terahertz technology market. China Unicom has begun research into Terahertz communication, one of the main 6 G technologies. The company, in collaboration with 20 other companies and research organizations, has formed a research organisation, the Millimeter Wave Terahertz Joint Innovation Centre. The research collaboration will create several demonstration projects and establish a dozen or more standards, helping to expand the terahertz market.
Drivers –Terahertz Market
