Abstract
Methods of solution for the wave equation in terms of series of integrals are simplified by means of an operator formalism. In this way the equivalence of series solutions given by Bremmer and Broer is easily proved. A new solution, valid for a large gradient of the refractive index, is given. The splitting of the solution in two partial waves travelling in opposite directions is discussed in connection with the expressions for energy density and intensity.
