题目一：Radio Maps for Wireless Communications andLocalization

内容简介：Radio maps have emerged as a critical enabler for next-generation wireless communication and localization systems. By characterizing the spatial variation of received signal strength, radio maps support a wide range of functions, including beamforming, resource allocation, UAV trajectory design, and source localization. However, constructing accurate radio maps in practice remains challenging due to the sparse, irregular, and noise-contaminated nature of real-world measurements.

题目二：Generalized Pinching-Antenna Systems: Basic Concepts, System Design Strategies, and Future Directions

内容简介：This talk introduces the concept and evolution of pinching-antenna (PA) systems and their generalized form, termed generalized pinching antennas (GPAs). Pinching antennas combine low-loss guided-wave transmission with flexible wireless radiation to dynamically reshape the wireless channel and create strong Line-of-Sight links. Building upon this foundation, the generalized framework extends the idea beyond dielectric waveguides to include leaky coaxial cable–based and surface-wave–based implementations, enabling a broader range of flexible antenna architectures. The talk covers the fundamental channel modeling, the impact of in-waveguide attenuation, and key system design strategies for both single- and multi-waveguide configurations. Finally, several open research directions for GPA-enabled 6G systems are discussed, highlighting their potential to bridge electromagnetic design and intelligent wireless networking.
