Physics-inspired neural network prediction of high-Q near-field spectra for roughness-engineered plasmonic metasurfaces

In plasmonic metasurfaces, structural roughness is conventionally regarded as a source of parasitic loss and degradation of surface lattice resonances (SLRs). Here, we demonstrate that roughness can be strategically harnessed as an active design degree of freedom, orthogonal to c...
