The electromagnetic plane-wave force on homogeneous materials having the possible set of constitutive parameter signs is evaluated. The force remains positive in all cases with loss, but a negative force results with gain. A negative force is shown to occur for an evanescent field when there is no component of the electric field in that direction. Both forces have significant magnitude and hence should be observable in experiments.
