A scattering spectroscopy apparatus, system and method employ guided mode resonance and a GMR grating. The perimeter of the slot being designed such that p=k\u03bbs where k is a whole number greater than 1 and \u03bbs the guided wavelength in the slot, the antenna comprising at least one first feed-line placed in an open circuit zone of the slot and a second feed-line placed at a distance d=\u03bbs4 from the first line, where n is an integer greater than or equal to zero. This transition will result in beginning or starting a dwell time. The panel may be made by assembling two plates on a fabric by gluing. The data structure may includes chapter management information for managing reproduction of the video data by chapters.
