Discrimination between two mechanisms of surface scattering in a single-mode waveguide
Discrimination between two mechanisms of surface scattering in a single-mode waveguide
Transport properties of a single-mode waveguide with rough boundary are studied by discrimination between two mechanisms of surface scattering, the amplitude and square-gradient ones. Although these mechanisms are generically mixed, we show that for some profiles they can separately operate within non-overlapping intervals of wave numbers of scattering waves. This …
