Abstract:
Pinching-antenna systems (PASS) represent an emerging class of flexible-antenna technologies for next-generation wireless communications. By utilizing low-loss dielectric waveguides to transmit signals and pinching antennas (PAs) with adjustable positions to radiate them into free space, PASS enables dynamic, energy-efficient, and spatially adaptive communication. This talk will introduce the fundamentals of PASS, including its signal modelling and transmission architecture. We will then explore several representative case studies involving both single-waveguide and multi-waveguide scenarios—covering pinching beamforming designs, multiple access strategies, and physical layer security (PLS) techniques. The talk will conclude with a discussion of key open problems and future research directions for PASS.
