| Abstract: | The problem of diffraction by a planar junction of thin layers covering a perfectly conducting substratum is considered, and
its asymptotic solution is constructed. The wave field in the vicinity of the junction of the layers is described by a function
of the boundary layer. Based on the asymptotics obtained, the generalized impedance boundary condition, which simulates thin
layers, and the contact conditions are derived. The uniqueness of the solution of a model problem is discussed. Bibliography:
