Abstract :
In a companion paper (see ibid., p.675-8, 1992), the authors analyzed time-harmonic plane wave scattering by finite periodic arrays of thin perfectly conducting infinite flat strips placed on the z=0 plane of a rectangular coordinate frame. In the presented paper, they address scattering from these arrays when the incident plane wave has a short pulse transient profile. Time domain hybrid (wavefront)-(Floquet mode) solutions have been generated. Numerical results are discussed.<>
