Terahertz Technology Applied in Mobile Communications

Abstract

Owing to its ultra-high frequency, the terahertz band becomes one of the candidate bands for 6G communication. In this chapter, the characteristics and application fields of the terahertz wave, especially the application in wireless communication, are introduced in detail. Firstly, the characteristics of the terahertz wave are briefly introduced, and then the terahertz technology, including terahertz devices and the main application fields of the terahertz wave, is introduced. Next, focusing on the application of the terahertz wave in the wireless communication system, it introduces two mainstream terahertz wireless communication systems, describes the key technologies, and finally describes the potential application prospect of the terahertz wave in the wireless mobile communication system.

Keywords: Device, Direct modulation, Solid-state, Terahertz wave, Wireless communications.
