Unleashing the THz Band: From Near-Field to Space

The 0.1–10THz band offers vast untapped spectrum for next-generation communication and sensing. Despite recent technological progress, challenges remain in utilizing frequencies above 100GHz. This talk explores innovative solutions for terrestrial and space-based THz systems. We discuss wavefront engineering for near-field links, featuring self-healing Bessel and Airy beams, and demonstrate the potential of THz frequencies for high-speed satellite networks, highlighting the upcoming TeraLink experimental mission.
