This work demonstrates new functionalities in flat optics using partially nonlocal metasurfaces, indicating advances in imaging and communication.
Overcoming the traditional trade-off between spatial control and high quality factors, a new class of multifunctional photonic crystals bridges the gap between local and nonlocal light manipulation. This work opens a new frontier in flat optics: the realm of partially nonlocal metasurfaces, paving the way for advanced imaging, communication, and analog optical computing.
