Abstract
We investigate how the dispersion and loss properties of a medium are altered when the medium is set into motion. Dispersive moving media is shown to give rise to unidirectional propagation in certain frequency ranges. Lossy moving media is shown to be maximally lossy for contra-directional propagation, at the velocity where the real part of the refractive index crosses zero. This work will serve to develop emerging spacetime metamaterials.
