Integrated Communications and Sensing in Terahertz Band: A Propagation Channel Perspective

Abstract

The rise of new requirements for future wireless systems is leading to a convergence of communication systems toward very high carrier frequencies, wide bandwidth, and massive antenna arrays. Understanding the properties of terahertz (THz) electromagnetic waves is critical for integrated communication and sensing (ISAC) system development and optimization. Therefore, in this paper, we investigate the propagation channel parameters and the applicability of terahertz electromagnetic waves for integrated communications and sensing. In doing so, we explore the new challenges and differences that arise when moving from systems operating at frequencies below the terahertz frequency bands.
