NEGATIVE INDEX

A ray of light is incident on a boundary between vacuum and material that (at that particular frequency) has dielectric constant ε=-1 and magnetic permeability μ=-1. (Stricly speaking, these quantities must also have imaginary parts. We will assume that they are very small.) The incidence angle is θ. What can you say about the direction of the reflected and the transmitted rays.
