IEEE International Geoscience and Remote Sensing Symposium, 2002

The backscattering from surface profiles approximating the crests of steep water waves has been modeled using diffraction theory. The diffractive backscattering from rounded-apex wedges is due to diffraction from curvature discontinuities, and can be predicted with apex radii as small as one-third of a wavelength using standard diffraction coefficients provided that heuristic corrections are applied to account for the small ...

Approximate high-frequency expressions for the currents induced on a perfectly conducting plane angular sector are derived on the basis of the incremental theory of diffraction (ITD). These currents are represented in terms of those predicted by physical optics (PO) plus fringe contributions excited by singly and doubly diffracted (DD) rays at the two edges of the angular sector.

  • Diffractive analysis of backscatter from wave-crest-like objects

    The backscattering from surface profiles approximating the crests of steep water waves has been modeled using diffraction theory. The diffractive backscattering from rounded-apex wedges is due to diffraction from curvature discontinuities, and can be predicted with apex radii as small as one-third of a wavelength using standard diffraction coefficients provided that heuristic corrections are applied to account for the small radii and finite surface conductivity. The same diffraction theory can also be used to model the backscattering from surfaces that approximate the early formation of a jet on a breaking crest, although accuracy is a bit poorer when the crest-feature radii are one-third wavelength. This confirms that the limitations found in a previous study are due to the limitations of the model itself, and not due to the averaging of surface curvatures that were needed to allow the application of the model.

  • ITD formulation for the currents on a plane angular sector

    Approximate high-frequency expressions for the currents induced on a perfectly conducting plane angular sector are derived on the basis of the incremental theory of diffraction (ITD). These currents are represented in terms of those predicted by physical optics (PO) plus fringe contributions excited by singly and doubly diffracted (DD) rays at the two edges of the angular sector. For each of these two contributions, additional currents associated to vertex diffracted rays are introduced that provide continuity at the relevant shadow boundary lines. The transition region of DD rays is described by a transition function involving cylinder parabolic functions. The asymptotic solution presented is constructed in such a way to satisfy far from the vertex the expected edge singularities, which tend to be the same as those predicted by the exact solution of the half plane. Numerical results are compared with the exact solution of the same problem and with moments method results for scattering from polygonal plates.

  • Phase synchronism possibility in optical fibers

    Optical fiber with Bragg grating inserted in fiber cladding is analyzed by means of volume integral equation method (VIE). Complex dispersion curves with two branches corresponding to positive and negative dispersion are simulated. The fiber parameters matched to phase synchronism conditions for weak Pockels- like nonlinearity are found.

  • Self-images of self-similar gratings

    Because the fractal density functions which represent Cantor and Sterpinski diffraction gratings can be build up in a similar way to the Walsh functions, that is through a multiplicative superposition of rectangular periodic components, they have self-images along the propagation direction. Here is shown this fact and an extension when we have Cantor gratings with equal dimension but different lacunarity is discussed.

  • Single-pixel coherent diffraction imaging with THz waves

    We propose and demonstrate single-pixel coherent diffraction imaging with ultrafast THz waves, whereby all the spatial frequency components processed by a spatial phase retarder are simultaneously measured by a fixed-location single-pixel detector.

  • Bistatic measurements of scattering from edges

    Measurements are presented of scattering from a 30- degree metal wedge and from a metal plate which has a thickness of 0.75 wavelength. The measurements were made on an indoor bistatic scattering range operating at 70 GHz. A comparison is made of the experimental data with computations based on Keller's geometrical theory of diffraction. For the wedge, there is good agreement of the measurements and computations over a range of scattering angles in which the scattered power changes by over 40 dB. For the plate, the measurements of scattering agree quite well with the computations based on single diffraction from each edge.

  • A micromachined vibratory sub-wavelength diffraction grating laser scanner
