A Frequency Dependent Ray Theory
Abstract
Practical computational procedures for obtaining ray theoretical solutions to the inhomogeneous Helmholtz equation resort to a well known approximation. The computational method presented here enables one to trace rays without resort to the ray theory approximation provided a solution to the Helmholtz equation is available by independent means. In other words, given a solution to the Helmholtz equation, the exact rays for that case can be computed. The new ray theory therefore serves, not as computational method, but as a new method of displaying solutions to the Helmholtz equation. Keywords: Ray theory; Acoustic propagation.
