Here, we show that corrugated graphene with sub-m period has the potential to generate synchrotron-like radiation in the THz frequency range. We perform electrodynamic calculation with a model of charges in periodic angular motion and demonstrate that significant output power levels can be obtained as well as geometrically tunable THz frequencies. We also report on the first technological fabrication of corrugated hBN-encapsulated graphene devices for synchrotron-like THz emission. We perform low-bias transport measurements at 4 K and show interesting deviation from transport in usual plane graphene.
