What this work contributes
Infrared plasmon interference images resolve CVD graphene grain boundaries. Electronic barriers scatter plasmons and impede electrical transport.
Where the evidence stops
The effective electronic barrier width is not an atomic boundary thickness or a universal graphene constant. Suggested tunable reflectors and phase retarders are possible applications, not a demonstrated propulsion system.
