Reflection of electromagnetic plane wave from a planar chiral nihility-chiral nihility interface is calculated as a special case of two different chiral media by assuming that permittivities and permeabilities of the both media approach to zero. That is, i → 0, µ i → 0, and chiralities κ i = 0, i = 1, 2. These results are used to find the geometrical optics reflected fields of a cylindrical chiral nihilitychiral nihility interface, when it is excited by a plane wave. Using the Maslov's method,
