Abstract

In a recent publication [J. Opt. Soc. Am. A 13, 1013 (1996)] a modified formulation of a rigorous Fourier-expansion eigenmode method was presented in TM polarization, which produces the correct effective refractive indices of form-birefringent stratified media in the lowest-order approximation. In this communication it is shown that a further refinement is consistent, for any angle of incidence, with the extraordinary nature of the TM-polarized wave in the quasi-static limit.
