Two-dimensional Green's function for a wedge with impedance faces

IEEE Transactions on Antennas and Propagation, 1997

The solution for the two-dimensional (2-D) Green's function for a wedge with impedance faces is presented. The important feature of this Green's function is that there are no restrictions on the locations for the source and observation points-they can be anywhere. Its development proceeds along two separate lines: one for when the source or observation point is far from the ...

  • Two-dimensional Green's function for a wedge with impedance faces

    The solution for the two-dimensional (2-D) Green's function for a wedge with impedance faces is presented. The important feature of this Green's function is that there are no restrictions on the locations for the source and observation points-they can be anywhere. Its development proceeds along two separate lines: one for when the source or observation point is far from the wedge vertex and another one for when it is close. Much of the effort that has been expended in these formulations has been in obtaining forms for the Green's function which are efficient to evaluate numerically. This involved deforming the various contours of integration so that they are rapidly convergent and separating the contributions from the numerous singularities that occur in the integrands and evaluating them in closed form. The formulations that are employed here allow for the individual field components such as the diffracted, geometrical optics, and surface wave components to be identified and studied individually so that a physical understanding for the various scattering mechanisms for the impedance wedge can be appreciated.

  • Localized surface plasmons in lamellar metallic gratings

    Surface electromagnetic modes of lamellar metallic gratings made of gold are analyzed both theoretically and experimentally in the 0.21.0 eV spectral range for p-polarized light. For deep enough grooves, we show how waveguide resonances that show no dispersion with parallel momentum appear in the photonic band structure of these surface plasmons. In these resonances the electric field is highly localized inside the grooves and is almost zero in all other regions. We also illustrate the existence of hybrid modes, combination of standing waves with propagating surface plasmon polaritons. Experimental evidence of the excitation of both kind of localized surface plasmons is given for lamellar gratings of period 3.5 /spl mu/m with grooves 0.5 /spl mu/m wide and 0.6 /spl mu/m deep.

  • Scattering from dielectric-coated impedance elliptic cylinder

    The scattering properties of an impedance elliptic cylinder coated with a homogeneous material are investigated analytically. The method of separation of variables together with the impedance boundary condition (IBC) are used to determine the field distributions in each region for both the TM and TE excitations. The technique can be easily extended to handle any number of layers. The behavior of the scattered field in the far zone is illustrated with numerical results for different core and coating material types, axial ratio, and electrical sizes.

  • Analysis of surface structures of a metal target from multi-pulse KrF laser ablation

    Summary form only given, as follows. Aluminum targets were ablated by focusing a KrF excimer laser (248 nm, 40 ns, <1.2 J) down to a spot size of 0.05 cm/sup 2/ with a fluence of approximately 4.9 J/cm/sup 2/. After a few tens of pulses, surface irregularities (corrugations and pits) progressively emerge, with size 1-100 /spl mu/m which is much larger than the laser wavelength. Such large scale surface roughness causes multiple reflections of the laser light, and may increase the absorption coefficient over a pristine, flat surface by an order of magnitude. Thus, as much as 16% (at room temperature) of the power of the KrF laser may be absorbed by the aluminum target. Scaling laws on the enhanced absorption due to surface roughness are derived. We have also examined various physical mechanisms that lead to these large scale surface structures. The most promising candidate appears to be hydrodynamic instabilities of intense plasma formation near to the surface. A model is developed which yields the growth rate as a function of wave number, thickness of molten layer, energy density and spatial extent of the surface plasma, and the thermophysical properties of the irradiated material. We found that there is a threshold of plasma energy density for the occurrence of the instability.

  • A new reflection and transmission analysis of a finite size frequency selective subreflector due to a finite source; a plane wave spectrum approach

    A new reflection and transmission analysis of a finite size frequency selective subreflector (FSS) due to a finite source located in the proximity of the FSS is presented. The field due to the finite source (in this case a corrugated feed horn) is first expanded in terms of the spectrum of the plane waves, and then, by employing the reflection and transmission matrices of the FSS the physical optics currents on a surface enclosing the FSS are constructed. From the currents and employing the field equivalence principle, the transmitted and reflected fields (scattered field) are found. The analysis presented is of importance to the design of advanced communication satellite antennas, where the FSS provides the multifrequency capabilities for the shaped reflector.

  • Modified emission of single semiconductor quantum dots by a two-dimensional metal grating structure

    The emission properties of single quantum dots are dramatically modified by electromagnetic interactions with surface plasmon polaritons propagating along a modulated metallic surface. The modified emission spectra and decay rates are measured in this system

  • Surface instability on a metal target from multi-pulse KrF laser ablation

    Summary form only given, as follows. Aluminum targets were ablated by focusing a KrF excimer laser (248 nm, 40 ns, <1.2 J) down to a spot size of 0.05 cm/sup 2/ with a fluence of approximately 4.9 J/cm/sup 2/. After a few tens of pulses, surface irregularities (corrugations and pits) progressively emerge, with size 1-100 /spl mu/m which is much larger than the laser wavelength. After hundreds of laser pulses, large scale wavelike patterns, on the order of 30 /spl mu/m, are observed on the aluminum surface. We propose that these wave patterns are caused by the Kelvin-Helmholtz instability at the interface of the molten aluminum and the plasma plume. A parametric study is given in terms of the molten layer's thickness and of the spatial extent and kinetic energy density in the laser-produced plasma plume. Also included is an estimate of the cumulative growth in a multi-pulse laser ablation experiment. These estimates indicate that the Kelvin-Helmholtz instability is a viable mechanism for the formation of the large scale structures. Once formed, these large scale surface roughness causes multiple reflections of the laser light, and may increase the absorption coefficient over a pristine, flat surface by an order of magnitude.

  • Computation of EM scattering from fractal rough surfaces using composite scattering model

    For the computation of electromagnetic scattering from a fractal rough surface, the authors consider the small perturbation method and a composite scattering model. A numerical simulation results are also given.

  • Polarization ratios anomalies of 3D rough surface scattering as second order effects

    A detailed analysis of the behaviour of electromagnetic scattering from various corrugated bidimensional surfaces is presented. We show that rigorous electromagnetic computations on two dimensional surfaces can in fact yield HH/VV polarization ratios greater than one, with values consistent with those observed experimentally. We also show that HH/VV ratios greater than one are ubiquitous in the case of surfaces of the form f(x, y)=f/sub 1/(x)+f/sub 2/(y), known as crossed gratings in optics. Theoretically and numerically, these surfaces are shown to produce backscattered returns for which the first order Rice/Valenzuela term vanishes for off axis incidence. The second order term becomes dominant and has the property that HH returns exceed VV returns for a significant range of incident angles. Our approach is based on the methods of O.Bruno and F. Reitich (see J. Opt. Soc. A., vol.10, p.2551-62, 1993) which yield accurate results for a large range of values of the surface height. In particular, these methods can be used well beyond the domain of applicability of the first order theory of S.O. Rice (1951). The error in our calculations is guaranteed to be several orders of magnitude smaller than the computed values. The high order expansions provided by these methods are essential to determining the role played by the second order terms as they show that these terms indeed dominate most of the backscattering returns for the surfaces mentioned. Classically, large HH/VV ratios were sought by means of first order approximations on one dimensional sinusoidal profiles. In that case, we show that the first order terms do not vanish and the first order theories predict the behaviour of the backscattered returns, for small values of the height to period ratio. However, in the case of a two dimensional bisinusoidal surface, strong polarization dependent anomalies appear in the scattering returns as a result of the contributions of second order terms since, in that case, the first order contributions vanish.
