Exploring the Properties of Reverberation Chambers in the THz Range: A Pilot Study

The rapid evolution of wireless communication technology and the emergence of 6G have led to the exploration of new segments of the electromagnetic spectrum, specifically the THz region. These high frequencies promise exceptionally high data rates, yet they also introduce substantial technical challenges. One primary challenge involves measurement techniques, encompassing component design, instrument manufacturing, and the creation of practical testing environments suitable for these frequencies. In this paper, we focus on employing reverberation chambers as testing environments within the THz region. Firstly, we examine the chamber's characteristics, particularly addressing losses up to 220 GHz. Subsequently, we present the hardware components and introduce a dedicated new mode stirrer designed for operation at these frequencies. The paper also offers insights and establishes a theoretical foundation for loss calculations within the reverberation chamber at high frequencies.
