Frequently Asked Questions:

What is Terahertz Technology?

Terahertz technology refers to the scientific and engineering discipline that deals with electromagnetic radiation in the terahertz frequency range, typically from 0.1 THz to 10 THz. This technology bridges the gap between microwave and infrared frequencies and offers unique properties, such as the ability to penetrate common non-conducting materials like plastics, clothing, and cardboard, while being non-ionizing and therefore safe for biological tissues. It is widely used for imaging, spectroscopy, and communication applications.

What are the primary applications of Terahertz Technology?

Terahertz technology finds diverse applications across multiple sectors. Key areas include non-destructive testing and quality control in manufacturing for detecting defects or foreign objects, security screening for concealed weapons and explosives, medical imaging for early disease detection and diagnostics, and pharmaceutical analysis for drug quality control and counterfeit detection. Additionally, it holds significant potential for high-speed wireless communication, particularly in the development of 5G and future 6G networks.

Why is Terahertz Technology considered safe for human use?

Terahertz radiation is considered safe for human use because it is non-ionizing, meaning its photons do not carry enough energy to break chemical bonds or cause ionization in biological tissues. This contrasts with X-rays or gamma rays, which are ionizing and can cause cellular damage. Terahertz waves interact with materials through molecular vibrations and rotations, making them suitable for non-invasive medical and security applications without posing health risks to individuals exposed.

What are the main challenges hindering the widespread adoption of Terahertz Technology?

Despite its potential, the widespread adoption of terahertz technology faces several challenges. These include the high cost of terahertz sources and detectors, which can be expensive to manufacture; the bulkiness and complexity of current terahertz systems, which limit portability; the relatively low power output of available sources; and the limited penetration depth of terahertz waves in certain materials like water or metals. Additionally, a lack of standardized regulations and a need for specialized expertise for operation and data interpretation also pose hurdles for market expansion.

How is Artificial Intelligence (AI) impacting the Terahertz Technology Market?
