Metasurfaces for Photonic Devices

Metasurfaces have attracted significant attention over the last decade owing to their broad capability to achieve exotic electromagnetic responses, and their potential as optical devices for wavefront control. Wide ranging materials may be used to form metasurfaces including noble and non-noble metals, oxides, ceramics, phase change materials, and semiconductors, permitting versatile and reconfigurable properties ideal for applications. This Special Topic highlights the state-of-the-art in metasurface photonic devices including recent advances in theory, numerical simulation, fabrication methods, and spectroscopic characterization that are advancing the field. Original research articles are accompanied by invited tutorials and perspectives that offer deep physical insight and provide an exciting outlook on future research.
