A 2-D (two-dimensional) Huygens surface is developed for the finite difference time domain (FDTD) algorithm, allowing the investigation of pulsed plane-wave scattering from arbitrary 2-D structures placed on or in an infinite dielectric slab. Example results are presented for scattering from a perfectly conducting strip on an infinite dielectric slab, and the results are compared with data computed via the method of moments. Additionally, the diffraction from a finite, saw-tooth dielectric grating on an infinite dielectric slab is investigated.
