The dispersion curves of surface waves controlled by normal modes have been widely used
for the retrieval of subsurface structures. However, only the S-wave velocity structures can …

based on the multidomain pseudospectral scheme, for the first time, to study the modal …

In this paper we consider the problem of computing the eigen-modes for the varying
refractive-index profile in an open waveguide. We first approximate the refractive-index by a …

In this paper, the smooth approximation of light waves is studied for an open optical
waveguide with a distinct refractive-index profile, which involves high-precision computation …
