Optics of Nonuniformly Moving Media
Full text linkA moving dielectric appears to light as an effective gravitational field. At
low flow velocities the dielectric acts on light in the same way as a magnetic
field acts on a charged matter wave. We develop in detail the geometrical
optics of moving dispersionless media. We derive a Hamiltonian and a Lagrangian
to describe ray propagation. We elucidate how the gravitational and the
magnetic model of light propagation are related to each other. Finally, we
study light propagation around a vortex flow. The vortex shows an optical
Aharonov--Bohm effect at large distances from the core, and, at shorter ranges,
the vortex may resemble an optical black hole.Comment: Physical Review A (submitted
