    "abstract": "Double-resonant extremely asymmetrical scattering (DEAS) is a strongly\nresonant type of Bragg scattering in two joint or separated uniform gratings\nwith different phases. It is characterised by a very strong increase of the\nscattered and incident wave amplitudes inside and between the gratings at a\nresonant phase shift between the gratings. DEAS is realised when the first\ndiffracted order satisfying the Bragg condition propagates parallel to the\ngrating boundaries, and the joint or separated gratings interact by means of\nthe diffractional divergence of the scattered waves from one grating into\nanother. This Letter develops a theory of non-steady-state DEAS of bulk TE\nelectromagnetic waves in holographic gratings, and investigates the process of\nrelaxation of the incident and scattered wave amplitudes to their steady-state\nvalues inside and outside the gratings. Typical relaxation times are\ndetermined. Physical explanation of the predicted effects is presented.",
