“…With the availability of frequency extenders of vector network analyzer (VNA) at the 100−500 GHz range (and more recently up to 1100 GHz) [17], [18], frequency domain channel sounding has been applied to investigate a multitude of more complex scenarios. In [19] the impact of blocking and diffraction has been described including a comparison of these effects at 60 GHz and 300 GHz.…”

“…The beam spot diameter from high-gain horn antenna with beam divergence holds a pivotal position for channel modeling in THz communications. For instance, larger beam spot size tends to reduce misalignment losses [17]. Moreover, the increase in beam spot diameter generates unwanted and measurement sophisticated reflections at local scatterers, reflectors or even at the measurement devices, thereby resulting in the so called ping pong effect [126].…”

In recent years, terahertz (THz) systems have become an increasingly popular area of research thanks to their unique properties such as extremely high data rates towards Tb/s, submillimeter localization accuracy, high resolution remote sensing of materials, and remarkable advances in photonics and electronics technologies. This article traces the progress of THz measurements, antennas and simulations, from historical milestones to the current state of research and provides an outlook on the remaining challenges.INDEX TERMS Channel modeling, history, MTT 70th anniversary special issue, on-chip antennas, raytracing, THz communications, THz measurements and simulations.This article has been accepted for inclusion in a future issue of this journal.

“…In [22], the authors experimentally evaluated the impact of deterministic beam misalignment in highdirectional indoor THz wireless systems. In [23] and in [24], the impact of beam misalignment in indoor THz wireless systems operating at 100, 300, 400, and 500 GHz in terms of channel coefficient degradation were calculated by means of experimental measurements.…”
