| Popis: | A new wave-vector-space method capable of finding electromagnetic wave propagation in bounded nonlocal media without using boundary conditions is used to find the modes of an optically active planar dielectric waveguide. Optical activity involves first-order wave-vector dispersion (nonlocality). The method finds how the altered nonlocal interaction close to the surfaces affects the waveguide modes. It is found that first-order effects of the surface layer nonlocality enter both the dispersion relation and the field profiles. The waveguide geometry is also used as an impetus to generalize several aspects of the wave-vector-space method. |
