Time: 10:00 a.m., Friday, May 30, 2025

Venue: Third Meeting Room, 1st Floor, Block A, Feicui Science and Education Building

Report Abstract:

The Pinching-Antenna System (PASS) represents a revolutionary advancement in flexible antenna technology, which enhances wireless communication by establishing strong line-of-sight connectivity, minimizing free-space path loss, and enabling dynamic reconfiguration of antenna arrays. This talk will introduce the basic principles of PASS based on a prototype and explore how PASS transforms communication systems from a conventional wireless paradigm towards a near-wired paradigm. The talk will also cover the physical principles and signal modeling techniques behind PASS, the activation method of pinching antennas, and the transmission structures. Several case studies will be discussed to showcase PASS capabilities, including performance analysis, beamforming design, and the integration of deep learning. Finally, the talk will highlight key research challenges and outline promising opportunities for future exploration in this innovative technology.
