Wave propagation control by spatial modulation of velocity has a long
history in optics and acoustics.
We address velocity-modulation control of electron wave
propagation in graphene and other two-dimensional Dirac-electron systems,
pointing out a key distinction of the Dirac-wave case. We also propose a strategy for
pattern transfer from a remote metallic layer that is based on many-body
velocity renormalization.
