Solutions of the Helmholtz equation given by solutions of the eikonal equation

G.F. Torres del Castillo, I. Rubalcava-García

Abstract


We find the form of the refractive index such that a solution, $S$, of the eikonal equation yields an exact solution, $\exp ({\rm i} k_{0} S)$, of the corresponding Helmholtz equation.

Keywords
