Plasmonic metamaterial time crystal.

Spatial photonic crystals (SPCs) are unique structures for light-matter interactions because they achieve a large and spatially periodic dielectric contrast on wavelength scales 1-4 .

Spatial photonic crystals (SPCs) are unique structures for light-matter interactions because they achieve a large and spatially periodic dielectric contrast on wavelength scales 1-4 . Their temporal analogues, photonic time crystals (PTCs), promise similar advances by…
