The objective is to construct and discretize (to fourth-order accuracy) a hybrid model for waveguide problems, where a finite difference method for inhomogeneous layers is coupled to a boundary element method (BEM) for a set of homogeneous layers. Such a hybrid model is adequate for underwater acoustics in complicated environments. Waveguides with either plane or axial symmetry are treated, which leads to (algebraically) two-dimensional problems. The main focus is on the collocated BEM.
