Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

The research group led by Professor Yijun Feng and Professor Ke Chen from Nanjing University reports a hybrid-phase strategy that unlocks broadband achromatic wavefront control for both circular ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...
