    "abstract": "Extremely asymmetrical scattering (EAS) is a highly resonant type of Bragg\nscattering with a strong resonant increase of the scattered wave amplitude\ninside and outside the grating. EAS is realized when the scattered wave\npropagates parallel to the grating boundaries. We present a rigorous algorithm\nfor the analysis of non-steady-state EAS, and investigate the relaxation of the\nincident and scattered wave amplitudes to their steady-state values.\nNon-steady-state EAS of bulk TE electromagnetic waves is analyzed in narrow and\nwide, slanted, holographic gratings. Typical relaxation times are determined\nand compared with previous rough estimations. Physical explanation of the\npredicted effects is presented.",
