Abstract. Two simple algorithms are proposed for deriving analytical expressions for the amplitudes of outgoing and inner waves in multilayer stepwise inhomogeneous structure by the incidence of two counterpropagating waves. The work of these algorithms is demonstrated on the analytical solution for three, four and five layer structure and numerical solve of waves propagation in structure with linear changing of† along its length. It is shown that these algorithms can applied to problems on propagation of electromagnetic waves in the cases of the normal and oblique incidence.

Keywords: wave propagation, multilayer nonuniform structure.
