摘要：

We numerically and experimentally investigate collective resonant responses of coherent metasurfaces consisting of planar random-flip asymmetrically split rings. The collective narrow band response becomes broader and eventually disappears with increasing the percentage of flipped split rings. The exploited physical mechanism is the degraded collective response due to random microscopic multipole excitation. Our study provides a method to construct random metasurfaces and is helpful to have an insight into their underlying physics.
