Abstract
An effective black-hole-like horizon occurs for electromagnetic waves in matter at a surface of singular electric and magnetic permeabilities. In a physical dispersive medium the horizon disappears for wave numbers with k>kc, and the effective geometry becomes flat. Nevertheless, it is shown that Hawking radiation is still emitted if free field modes with k>kc are in their ground state.
