Wavefront-selective Fano resonant metasurfaces被引量：7
《Advanced Photonics》2021年第2期78-88,共11页Adam Overvig Andrea Alù 
Fano resonances are conventionally understood as sharp spectral features with selectivity in the momentum-frequency domain,implying that they can be excited only by plane waves with specific frequencies and incident a...
