A Multidisciplinary Approach to Topology Transfer in Structured Radiation (IMAGE)
Caption
The project brought together researchers from multiple institutions with expertise in electron-beam control, slow-wave structures, electromagnetic simulation, optical diagnostics, and topological analysis.
Sun-Hong Min conceived the study and designed the experiment. Min, Matlabjon Sattorov, and Dongpyo Hong conducted simulations and theoretical analysis. Jin Pyung Kim and Ohjoon Kwon fabricated the slow-wave structures, while Ilsung Cho, Seonmyeong Kim, and Inkeun Baek supported electron-beam diagnostics. Seunghyuk Park and Young Joon Yoo contributed to optical measurements. Corresponding author Sang Yoon Park supervised the project, with all authors contributing to discussion and manuscript preparation.
Together, the team generated structured radiation, verified its orbital angular momentum, reconstructed its polarization topology, and assessed reproducibility, demonstrating the value of multidisciplinary collaboration in advanced photonics research.
