Abstract
The question whether main electrodynamics laws accept the existence of materials with negative ɛ and µ is considered. An obstacle to this is the negativity of the wave energy density W in the theory of such media. It is shown that an attempt to change W sign only worsens the situation since it leads to the conflict of signs in the continuity equation.
