Terahertz (THz) communication refers to the use of electromagnetic waves in the terahertz frequency range, typically between 0.1 and 10 THz, for data transmission. This frequency lies between the microwave and infrared spectrums and has unique properties that make it suitable for high-speed, short-range communication. Terahertz communication is an emerging field that promises a wide range of applications, especially in conjunction with nanotechnology.
