Intelligent THz Systems: Orchestrating Time, Frequency, and Space for Next-Generation Wireless Networks

This section integrates the fundamental RF concepts covered throughout the bootcamp to demonstrate the design of intelligent terahertz communication and sensing systems. We begin by addressing the temporal and spectral dimensions of THz links, including wideband modulation schemes, synchronization challenges, and channel estimation techniques specific to frequencies above 100 GHz. The presentation then explores the spatial dimension, examining how antenna arrays, metasurfaces, and reconfigurable intelligent surfaces (RIS) can be leveraged to overcome the severe path loss inherent to THz bands. We'll demonstrate how beamforming transitions from far-field to near-field regimes at these frequencies, fundamentally changing our approach to spatial signal processing.
