The frequencies within the terahertz range, known as the terahertz “gap,” have been relatively unexplored compared to the extensive research and technology utilizing radio, microwave, and infrared waves. This gap is so named by scientists due to the scarcity of knowledge and applications in this frequency range. However, recent advancements have paved the way for the exploration of this untapped potential. In the past, the only devices capable of emitting or detecting terahertz waves were as large as airport body scanners. Now, with the introduction of the iTeracare terahertz device, numerous benefits emerge.
