New York, March 18, 2022 (GLOBE NEWSWIRE) — Reportlinker.com announces the release of the report “Global Terahertz Technologies Market – Growth, Trends, COVID-19 Impact, and Forecasts (2022 – 2027)” – https://www.reportlinker.com/p06246204/?utm_source=GNW
22% during 2022-2027 (henceforth referred to as the forecast period). Terahertz technology is an emerging and growing field with potential for developing applications varying from passenger scanning at an airport to large digital data transfers and has been reflecting significant advancements on the scientific front. Terahertz (THz) radiation exhibits three unique properties, which stimulate the development of the whole terahertz industry.

Key Highlights
The market is witnessing various technological advancements, with researchers across the globe developing new ways to utilize terahertz energy in developing advanced devices/systems. Recently in February 2022, a device was created by researchers enabling to electronically steer and focus a beam of THz electromagnetic energy with high precision. This opens the door to real-time, high-resolution imaging devices that are a hundred times smaller than the size of other radar systems and robust than other optical systems. The device was demonstrated by the researchers by generating 3D depth images of scenes.
Further, the rising concerns regarding security systems across a variety of industries have created a dire need for efficient solutions that are eventually driving the growth of the market. The comparative niche market potential of the THz technology has been primarily implemented in applications such as security imaging and non-destructive testing (NDT). The non-ionizing and non-invasive radiations of the THz waves have rendered them immensely useful in the healthcare industry.
The ability to perform partial or full-body scanning and other related security screening without any radiation on vital elements are one of the significant factors driving the adoption of the terahertz technology in the security industry. The technology is witnessing considerable adoption in the airport screening vertical, helping to increase the screening throughput with high proven detection performance. As per the statistics published by the Canadian Air Transport Security Authority (CATSA), the number of passengers screened per hour at Canadian Airport increased to 217 per hour in 2020 from 159 per hour in 2016. However, the same number amounted to 102 passengers in FY 2021, dropping by 53% compared to 2019 levels due to the COVID-19 pandemic.
Various other airports, such as the Dubai International Airport, also get a huge inflow of passengers. In February 2022, the airport reported that it had received around 29 million passengers in 2021. Therefore, the easing of travel restrictions and the subsequent increase in national and international travel is expected to increase the usage of terahertz technology in the security sector.
With the outbreak of the COVID-19, the terahertz technology market is expected to witness growth with its major application in healthcare, biomedical, and security application. With a limited supply of COVID-19 testing kits in countries such as India and other parts of the world, people with mild symptoms are less likely to be tested. In order to tackle this issue, in May 2020, a team of researchers from the Defence Research Development Organisation (DRDO) and North Eastern Hill University is working on developing artificial intelligence-based terahertz radiation (t-ray) scanning unit to address the limitation of the infrared thermal scanner in the accurate and early detection of coronavirus patients.

Key Market Trends

Defense and Security is Expected to Witness Robust Market Growth

In today’s security environments, the ability to identify threats like hidden weapons body-worn explosives is a strong operational need. Owing to the growing emphasis on imaging concealed explosives, Terahertz technology for security and defense-related applications has recently experienced an increase in interest. The ability to detect and identify objects hidden behind barriers is one of THz technology’s core features. At airports or other security-critical places, dangerous non-metallic substances like ceramic knives or plastic explosives can now be detected with terahertz beams. This is possible because T-rays get through clothes but cannot get through the upper skin (because of the water content).
Additionally, metal detection and X-ray bag scanning are time-consuming processes. It becomes more difficult in the case of public transportation hubs wherein there are lots of movement. Hence there is a need for technological solutions that can perform security checks even at a distance from the potential source. Terahertz technology allows the scanning of a large number of people without requiring them to stop for a security check, thereby offering a solution to these challenges.
Further, in response to the urgent demand for efficient, safe, and speedy imaging in remote security screening applications, a new sub-terahertz security body scanner was developed by researchers in March 2020. This new 100-GHz security scanner presented the test results, which demonstrate that it can perform through-garment detection at standoff ranges of 3–6 m with a respective lateral resolution of 3–6 cm. The depth of the field of the system has been determined experimentally to be approximately 30 cm. Such initiative at remote places such as in the airport is highly recommended. THz sensors’ conceivable military applications are broad for intelligence, surveillance, and reconnaissance (ISR), including detection of isolated personnel behind enemy lines, fixing targets, and terminal guidance of precision weapons.
In a non-combat environment, THz could be used to help detect plastic or minimal metal land mines on current or former battlefields. Most anti-personnel mines are a combination of metal and plastic (and manufactured to avoid detection by metal detectors). The current technology for land-mine detection requires analysis of soil temperature and is measured in three dimensions, which is then injected into cumbersome software algorithms that make rough estimates with limited confidence. This detection technique uses Field Programmable Gate Array (FPGA) technology. THz spectroscopic imaging is one of the logical alternatives to FPGA, as it can detect almost any material under the right conditions with relatively high confidence.
Air surveillance radar systems are another technological pairing that is beginning to be explored as the potential use case for THz imaging. According to some articles released by the South China Morning Post, China North Industries Group Corporation, one of the country’s largest arms manufacturers, successfully tested THz instruments capable of detecting stealth aircraft.
China’s past pursuits of foreign and dual-use technologies suggest that the country will continue to grow its THz technology in competition with other international powers such as the US. The radiation produced, or ’T-rays,’ can penetrate the composite metals in examining underlying aircraft metals. These metals are specifically used for certain types of aircraft, making the process of finding and positively identifying any detectable substances.

North America is Expected to Hold a Major Market Share

The United States is considered to be a key market for terahertz technologies, primarily owing to the growing homeland security issues, investments in defense, and R&D. In addition, the stringent government regulations regarding the safety and production of aerospace technologies in the US and the growing automotive and aerospace industries are driving the market for THz technologies in the regional market.
According to the data provided by the US Department of Commerce, the US aerospace industry contributed USD 118.5 billion to the American economy in export sales. It is anticipated that for the next 20 years, the number of large commercial planes may witness 3.5% growth per year, to reach a total of 34,000 units, which is valued at around USD 4.5 trillion. Such heightened demand from the aircraft industry is a significant driver for the inspection systems’ growth based on the terahertz technology. The increase in helicopters and commercial aircraft production in the United States is expected to drive the market. The aerospace industry of the US exports more than 60% of all aerospace production. US Air Force researchers are looking into technologies for future line-of-sight air-to-air communications and networking at frequencies higher than 100 GHz to help aircraft exchange mission-critical battle-management information. For the same, Air Force experts are expected to test terahertz communication technologies through modeling and simulation.
Over the past several years, the expectations relating to delivering a large amount of complex data faster and at high quality are increasing, utilizing revolutionary antenna systems. The National Science Foundation (NSF), in February 2022, has awarded a USD 365,000 grant to the Department of Electrical and Computer Engineering of FIU to speed up the process. The study is being investigated by Professor Stavros Georgakopoulos, who is the director of the Transforming Antennas Center and the RF Communications, mm-Waves, and Terahertz Lab.
Further, the EMS (Electromagnetic spectrum) is critical to daily activities and encompasses all known and measurable wavelengths and frequencies. Due to its inherent capability to link warfighting equipment, electronics, and subsystems together, the US and its adversaries have begun to understand the prime importance of exploiting EMS dependencies. If harnessed correctly, the THz band of the EMS can accelerate the military capabilities ahead of an adversary.
Canada is expected to witness significant growth in demand for the technology due to an increase in the demand for security screening equipment across various public places. For instance, Canadian airlines screen passengers before they board flights bound for the country. Air Canada’s union, which is the Canadian Union of Public Employees (CUPE), announced additional pre-flight screening by making flight attendants responsible for the screening. Furthermore, AG recently announced the expansion of its manufacturing facility in Canada. The company trained personnel assigned.
