Abstract: Surface waves, which are locally a combination of inhomogeneous waves, are found as an immediate consequence of the bounded beam representation in terms of complex harmonic waves. Decay and velocity of these waves can be obtained directly from the separation of the reflected field into an attendant reflected beam and an interface wave component. The influence of the beamwidth parameter of the bounded beam on the decomposition into complex harmonic waves explains the nonobservance of particular Lamb waves at certain angular regions, e.g. near the longitudinal critical angle. This representation holds the possibility to predict optimum parameters to observe strong Lamb wave radiation which can be of great importance in the field of acoustic microscopy.
