Hf. Pinheiro et al., Full-vectorial FE-BPM approach for the analysis of anisotropic medium withoff-diagonal permittivity terms, MICROW OPT, 25(1), 2000, pp. 12-14
A full-vectorial finite-element propagation method, spurious mode free, wit
h off-diagonal elements in the permittivity tensor is presented for the fir
st time. Comparison with experimental data obtained from the alignment of t
he principal axes in birefringent fibers validates the method. (C) John Wil
