This paper treats the derivation of a two-dimensional differential equation, which describes the
phenomenon of combined refraction - diffraction for simple harmonic waves, and a method of solving this
equation. The equation is derived with the aid of a small parameter development, and the method of
solution is based on the finite element technique, together with a source distribution method.
