Metasurfaces and other photonic structures with subwavelength features enable the manipulation of light in unprecedented ways. After the first generation focusing on monofunctional operations, persistent efforts have led to the design and realization of metasurfaces with multiple functionalities, demonstrating great promise for various applications. This session focuses on the emerging applications related to multi-functional metasurfaces and photonic structures, opening new possibilities for creating compact, multifunctional optical devices for imaging, information, energy and beyond.
