R. Perezalvarez et al., SIMULTANEOUS SURFACE GREEN-FUNCTION MATCHING FOR N INTERFACES, Journal of physics. Condensed matter, 7(10), 1995, pp. 2037-2049
The method of surface Green function matching (SGFM) is extended to th
e case of an arbitrary number N of interfaces so that all the SGFM for
mulae are obtained in a compact N x N matrix (or supermatrix) form rea
dy for practical calculations. As an example, shear (surface horizonta
l) waves in a Ni-W-AI-Ni structure are studied by a straightforward ap
plication of the general formulae. The range of applications of physic
al interest is stressed.
