Asymptotic forms of the Ursell edge waves on a gently sloping beach
arXiv:2607.12289
Abstract
It is shown that the asymptotics of the Ursell trapping modes on a sloping beach of small slope angle alpha coincide with the inverse Fourier transform of standard WKB exponentials, i.e., the Maslov canonical operator, as alpha tends to 0.
