Mata Mendez F. Chavez Rivas J. Sumaya Martinez Física, Astronomía y Matemáticas gratings scattering Diffraction electromagnetic optics Diffraction of an obliquely incident TE-polarized Gaussian beams by N equally spaced slits (finite grating) with conducting substrate istreated. The substrate can be either vacuum or conductor. The diffracted and scattered patterns, the transmission and reflection coefficients, and the normally diffracted energy are analyzed as a function of several optogeometrical parameters. Particularly, the coupling between slits and the influence of the substrate is considered. We have found that, when the substrate is a conductor, the grating equation in reflectionpredicts with good precision the angular positions of the orders of a finite grating; the angular positions of these orders are independents ofthe beam width, the spot position on the finite grating, and the conductivity of the substrate. Besides, the envelope of the reflected energy is conserved constant when the position of the spot is changed. 2004 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57062708 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
