Negative electromagnetic plane-wave force in gain media.
It is shown that a uniform electromagnetic plane wave can exert a negative force on a homogeneous medium with gain when there is no component of the electric field in that direction. A physical interpretation for this force is given, along with an estimate of the strength achievable in an experiment.
