Abstract
A physical realization of scattering by -symmetric potentials is provided: we show that the Maxwell equations for an electromagnetic wave travelling along a planar slab waveguide filled with gain and absorbing media in contiguous regions, can be approximated in a parameter range by a Schr\"odinger equation with a -symmetric scattering potential.
