Toward 6G with Terahertz Communications: Understanding the Propagation Channels

Abstract

This article aims at providing insights for a comprehensive understanding of terahertz (THz) propagation channels.Specifically, we discuss essential THz channel characteristics to be well understood for the success of THz communications.The methodology of establishing realistic and 6G-compliant THz channel models based on measurements is then elaborated on, followed by a discussion on existing THz channel measurements in the literature.Finally, future research directions, challenges and measures to enrich the understanding of THz channels are discussed.
