摘 要 对未被分配的空闲频谱资源的需求增长,将不可避免地使无线通信系统的
工作频率向更高频率的太赫兹(THz)频段发展。大数据的瞬时传输将采用更高的载波频率,
以满足高传输速率的需求。大量的研究表明,THz 技术在通信领域的应用与当今比较成熟的
微波通信和光纤通信相比,具有更多的优点,比如说,传输速率高,方向性好,安全性
高,散射小,以及穿透性好等。文章总结了THz 通信的特点及其适用领域,综述了近几年国
际上THz 通信研究最新进展,给出了未来THz 通信系统可能的发展趋势。

Abstract The increasing demand on unoccupied and unregulated spectral band resources
will inevitably lead to the extension of wireless communication operation towards the higher terahertz
(THz) frequency range. Higher carrier frequencies will allow for instantaneous transmission of huge
amounts of data to satisfy the demand for high transmission rates. A large number of studies have indi-
cated that, compared to optical fiber and microwave communications, THz communication has more
advantages, such as high transmission rate, better directionality, high security, low scattering, and
good penetrability. We review the progress in THz communication technology over the past few
years, as well as possible future trends.
