Abstract: (1445 Views)
In most theoretical studies on the interference and diffraction of light, impact of aperture thickness on the intensity pattern is ignored. In this paper, by considering the aperture as an optical waveguide, we investigate the intensity pattern of Young’s double-slit experiment for the apertures with finite thickness. Our results show that, in the case of normal incidence, the intensity pattern is symmetric and its peak and width are respectively smaller and wider than the pattern for the case of zero-thickness apertures. Moreover, our studies show that, based on the aperture thickness and width, interference pattern can be very different, when aperture illuminated by oblique radiation.
