"bound states in the continuum/ local–nonlocal transitions: improve light-matter interactions, unlocking ultra-narrowband wavefront shaping, precise spectral decoupling multiplexing, pixel-level color routing, for high-performance displays... structural color applications: resonant silicon nanoantennas suppress higher-order multipole modes for pure, bright colors with enhanced saturation/ resolution... broadband non-resonant capabilities + spectrally selective resonant meta-devices: AR/VR, imaging, photonics"
