Terahertz Radiation is a type of electromagnetic radiation that falls between microwave and infrared frequencies, typically ranging from 0.1 to 10 THz. It has unique properties that allow it to penetrate various materials, making it useful for imaging and sensing applications. This radiation is increasingly being explored in fields like medical imaging, security screening, and communications. Its ability to detect substances without harmful effects makes it a promising tool for non-invasive analysis and monitoring in various industries.
