Abstract
The surface Green's-function matching (SGFM) method for discrete syste ms is extended to the case of arbitrary multilayer structures, so that matching is simultaneously effected at an arbitrary number N of inter faces. In this way all the SGFM formulas are obtained in a compact 2N x 2N supermatrix form, ready for practical calculations. As an illustr ation, the vibrational properties of multilayer one-dimensional system s are considered.
