Scattering of electromagnetic fields by a defect layer embedded in a slow-light periodically layered ambient medium exhibits phenomena markedly different from typical scattering problems. Such a medium, constructed by Figotin and Vitebskiy, possesses a “frozen mode” at a frequency within a pass band, where the dispersion relation has a flat inflection point. The slow-light regime is characterized by a 3×3 Jordan block of the monodromy matrix.
