   Studies are done for structural non-stability of correct problem solution for the incidence of "almost" plane electromagnetic wave on "almost" plane-layered medium with "super small" absorption. Problem of normal incidence of plane wave on a plane layer of lossless dielectric investigated. Critical point at zero value of e is discovered. Solution of the problem depends qualitatively on values of of small parameters near this point. Dielectric with e near zero value is considered as a set of uniform dielectric spheres without central symmery. These spheres are put one into one in order to take curvature of the surface e-const into account.
