Some ray and intensity solutions in the complex plane
This paper presents a method to test range-dependent ray-tracing programs. The method is based on complex-function theory. From an analytic function that has a zero point at the emitter, expressions for sound speed, ray paths, travel time, and intensity can be derived. The intensity expression is very simple and also applicable to caustic points. Two examples are given.
