How are you blending ray and wave based optics? The two are generally incompatible

A ray tube has a (complex) field value associated with it. You simply add together the contributions. It is the basis for Keller's Geometrical Theory of Diffraction method that is widely used (in its modern form, the Uniform GTD) in antenna design, radar scattering, etc.
