Metrology for THz Communications

This open access book provides a state-of-the-art overview of metrology for upcoming THz communications, considered a key component of next generation wireless communication systems. Effective methods to conduct and evaluate measurements are crucial for the advancement of THz communication systems. However, at the start of the project in 2019, metrology at THz frequencies was still in its infancy, and thus far had only addressed detector calibration to characterize ultrafast devices as well as measuring uncertainty analyses of different spectrometer types available at THz frequencies. This book highlights how the grand challenge of metrology in THz communication measurements was addressed systematically in the publicly funded project DFG FOR 2863 Meteracom (Metrology for Terahertz Communications). It delves into four distinct and foundational project areas: traceability to the International System of Units (SI), characterization of the measurement system itself, metrological characterization of the RF components and the propagation channel, and measurements required for enabling the functionality of THz communications.
