CAUSTIC SURFACE ANALYSIS FOR A GRADIENT-INDEX LENS.

Academic Article

Abstract

  • General formulas for the energy flux density and the caustic surfaces formed by light rays propagating in a gradient-index medium are presented. For the radial gradient index of refraction, n**2(r) equals N//0**2 minus b**2r**2, where N//0 and b are constants, analytical expressions are presented for the energy density along the ray path in a medium and for the caustic surfaces produced by the medium. As an application, the caustic surfaces formed by collimated light rays incident upon a converging Wood lens are analyzed.
