Abstract
The paper presents a consistent method for modelling the
changes in macroscopic parameters produced by material and impurity modified
surfaces. The method, based on the surface fluctuation waves techniques of
lattice displacements, is structurally suited to accommodate a variety of
conditions existing at real surfaces, including inhomogeneity through the
depth and topographic irregularities. The resulting model formulation
provides a basis for an interpretation of the observed surface wave
propagating properties and is especially useful to obtain SAW velocity
dispersion.
