Abstract
The backscattering line shape is analytically predicted for
thick disordered medium films where, remarkably, the medium configuration is
periodic along the direction perpendicular to the incident light. A blunt
triangular peak is found to emerge on the sharp top. The phenomenon roots in
the coexistence of quasi-1D localization and 2D extended states.
