几十年来，微波工程技术在亚毫米（submm）波或太赫兹（THz）范围内（约300 GHz-3 THz）的主要作用一直是优化用于天文学、地球科学和等离子体诊断的分子光谱测量的组件和系统的性能[1]。光谱学之外的太赫兹应用的发展要慢得多。太赫兹频率的超高带宽通信可能拥有最强大的市场力量来支持它，但在原型阶段之后还没有部署任何系统，这可能是因为商业亚毫米波组件不可用，将它们与现有通信硬件集成的挑战，以及通常严重的大气衰减。
For decades, the principal role of microwave engineering techniques in the submillimeter (submm)-wave, or terahertz (THz), regime, spanning about 300 GHz-3 THz, has been to optimize the performance of components and systems used in molecular spectroscopy measurements for astronomy, earth science, and plasma diagnostics [1]. THz applications beyond spectroscopy have been much slower to develop. Ultrahigh bandwidth communication at THz frequencies may have the most powerful market forces to support it, but no systems have been deployed beyond the prototype stage, likely because of the unavailability of commercial submm-wave components, challenges with integrating them with existing communications hardware, and the often severe atmospheric attenuation.
