“…The effective boundary conditions can then be used to proceed with a specialized hyperbolicelliptic formulation for the studied Rayleigh-type waves, which was originally established in [16] using the symbolic Lourier approach (see e.g. [9] and references therein) and further developed in [17] starting from a slow time perturbation of the eigensolution for a homogeneous surface wave of arbitrary profile, see [18] and also earlier publications [19,20], as well as more recent papers including [21][22][23][24][25][26][27][28]. The general asymptotic methodology of extracting the contributions of surface, interfacial and edge waves from overall dynamic responses induced by prescribed loads is exposed in [29], with the effect of anisotropy addressed recently in [30].…”
