Researchers at Seoul National University‘s Intelligent Wave Systems Laboratory, led by Sunkyu Yu, are investigating how disorder can be used to control light scattering. Their study, “Non-Hermitian stealthy hyperuniformity,” extends established hyperuniformity concepts into non-Hermitian materials containing gain and loss, finding that correlations between material properties can influence scattering direction and symmetry.
The team used Tidy3D to perform full-wave electromagnetic simulations of large disordered scatterer assemblies, confirming that designed scattering-suppression symmetries remained visible. They also tested a passive alternative using low- and high-loss materials, aiming to make the approach more experimentally practical for disordered photonics and metasurfaces.
