Abstract

In a companion paper at this meeting, we have investigated wave-oriented processing techniques which extract from frequency domain (FD) scattering data for truncated periodic strip gratings the wave phenomenology that ties features in data to scattering mechanisms responsible for these features. The present paper explores time domain (TD) wave-oriented processing techniques for scattering by such gratings due to a pulsed incident plane wave. Time (t) - frequency (ω) phase space distributions implemented via windowed transforms now extract from the TD data new phenomenologies which are interpreted in terms of novel TD Floquet modes (FM) and TD-FM edge diffractions from the grating aperture truncations. This is in agreement with the previously developed analytic TD scattering models.
