being the electric-field component perpendicular to the surfaces. Numerical calculations are given for the power dependence of the propagation wave vector. For sufficiently larged/ (: wavelength) we have found regions with multiple solutions corresponding to the same power flow. This suggests possible applications to optical devices. |
