On the Diffraction of an Arbitrary Pulse by a Wedge or a Cone*
By virtue of Green's Theorem, it is shown that for the diffraction of an arbitrary two-dimensional incident pulse by a wedge of angle n, the ratio of the resultant velocity potential to the corresponding value of the incident pulse at the corner of the wedge at any instant is equal to 2x/ (2x — n); and that for the diffraction of a threedimensional pulse by a cone of solid angle u>, the ratio a...
متن کاملE-Polarized Diffraction by Dielectric Wedge
Geometrical optics (GO), the most widely used tool in analysis of high frequency electromagnetic problems, provides the first term of an asymptotic series solution to the Maxwell's equations [1]. It is implemented completely by employing the ordinary ray-tracing technique. To include the second asymptotic term systematically, Keller [2] suggested a generalization of the Fermat's principle on di...
متن کاملDiffraction by a right-angled impedance wedge
[1] A plane electromagnetic wave is incident at an oblique (skew) angle on a wedge of open angle 3p/2 with scalar face impedances, the same on both faces. When the theory previously developed for wedges of arbitrary angle with tensor face impedances is specialized to this case, the analysis simplifies, and the resulting expressions for the geometrical optics, surface wave and diffracted fields ...
متن کاملA Note on Point Source Diffraction by a Wedge
The object of this paper is to give new expressions for the wave field produced when a time harmonic point source is diffracted by a wedge with Dirichlet or Neumann boundary conditions on its faces. The representation of the total field is expressed in terms of quadratures of elementary functions, rather than Bessel functions, which is usual in the literature. An analogous expression is given f...
متن کاملA Green's function for diffraction by a rational wedge
In this paper we derive an expression for the point source Green's function for the reduced wave equation, valid in an angular sector whose angle is equal to a rational multiple of 77. This Green's function can be used to find new expressions for the field produced by the diffraction of a spherical wave by a wedge whose angle can be expressed as a rational multiple of n. The expressions obtaine...
