Abstract
TORRES DEL CASTILLO, G.F. and RUBALCAVA-GARCIA, I.. Solutions of the Helmholtz equation given by solutions of the eikonal equation. Rev. mex. fis. [online]. 2017, vol.63, n.3, pp.211-213. ISSN 0035-001X.
We find the form of the refractive index such that a solution, S, of the eikonal equation yields an exact solution, exp(i 𝑘 0 𝑆), of the corresponding Helmholtz equation.
Keywords : Helmholtz equation; eikonal equation.
