COMPUTATION OF COMBINED REFRACTION - DIFFRACTION

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