Spacetime Mapping of Spatially Sustained Polariton Under Time-Varying Excitation
Using terahertz near-field nanoscopy, we demonstrate that temporal shaping of plasmon polaritons in graphene effectively suppresses their spatial decay. Our experiments and simulations reveal a universal principle for spacetime wave engineering, broadly applicable in photonic, acoustic, plasmonic, and quantum systems.
