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 Schrodinger equation with a -symmetric scattering potential.

Nonlinear waves in PT -symmetric systems (2016, methodology): “Ruschhaupt, Delgado, and Muga (2005) noticed that if a medium where a light pulse propagates has an even refractive index profile and odd gain-loss landscape, then one can construct an optical analog of PT -symmetric quantum mechanics.”
