Speech Title: Generative AI for Wireless and Energy Systems: A Diffusion Model Perspective

Abstract: Diffusion models have rapidly evolved from image generators into a general framework for modeling complex data distributions. This talk presents three complementary directions that extend diffusion models beyond conventional generation and toward system-level intelligence. First, we revisit the reverse diffusion process through the lens of mean-field games, where denoising is reformulated as an optimal population-level transport problem between noise and data distributions. This perspective connects diffusion generation with controlled distribution evolution, saddle-point optimization, and coupled HJB–FPK dynamics. Second, we show how latent diffusion inpainting can reconstruct UAV radio maps from sparse and partial observations. By combining UAV-based sensing, spatio-temporal latent diffusion, and radio map reconstruction, diffusion models become a tool for recovering hidden wireless environments under limited coverage and dynamic sensing constraints. Third, we introduce socio-aware diffusion for residential load data generation, where social attributes guide controllable generation for disadvantaged or data-scarce communities. Through global-personalized multi-step diffusion and fairness-oriented adversarial training, the model generates realistic and diverse electricity-consumption patterns while improving downstream forecasting and reducing data imbalance. Together, these works highlight a broader view of diffusion models: not merely as sample generators, but as controllable and conditional for reasoning about evolving distributions in large-scale infrastructure systems, including wireless networks and smart grids.

Speech Title: Decoupling Multi-Antenna Systems with Dielectric Resonantors

Abstract: Mutual coupling between closely spaced antennas is a fundamental limitation in MIMO systems, in which spectral efficiency is gained by the use of multiple antennas at both ends of the link. As the element spacing is reduced below roughly half a wavelength, a rapid increase in the coupling between adjacent ports is observed, and the impedance match, the radiation efficiency, and ultimately the channel capacity are degraded. Most decoupling techniques reported to date rely on additional metallic structures—parasitic elements, defected ground planes, or neutralization lines—by which the complexity is increased and the antenna geometry itself is often constrained. In this talk, we show that mutual coupling can be controlled by dielectric resonators, which are employed here in a decoupling role rather than as the radiating element of the antenna. Radiation from these resonators is not eliminated; rather, it is the coupling path between antenna ports that is deliberately engineered through their resonant modes. A modal analysis of the dielectric resonator is first carried out, from which the interaction between its resonant modes and the fields of adjacent antenna elements is established. On the basis of this result, dielectric decouplers are designed by which mutual coupling is suppressed without any additional metallic structure and without restriction to a particular antenna type. Finally, we show that the same degrees of freedom can be exploited in the polarization and radiation pattern of the elements, which indicates a broader role for dielectric resonators in compact multi-antenna systems.
