Rigorous Expressions for the Equivalent Edge Currents
An exact form for the equivalent edge current is derived by using the axioms of the modified theory of physical optics and the canonical problem of half-plane. The edge current is expressed in terms of the parameters of incident and scattered rays. The analogy of the method with the boundary diffraction wave theory is put forward. The edge and corner diffracted waves are derived for the problem...
متن کاملEdge of the Wedge Theory in Hypo-analytic Manifolds
This paper studies microlocal regularity properties of the distributions f on a strongly noncharacteristic submanifold E of a hypoanalytic manifold M that arise as the boundary values of solutions on wedges in M with edge E. The hypo-analytic wave-front set of f in the sense of Baouendi-Chang-Treves is constrained as a consequence of the fact that f extends as a solution to a wedge.
متن کاملAlgorithm of Diffraction for Standing Tree based on the Uniform Geometrical Theory of Diffraction
Manuscript received September 11, 2011 * Corresponding author; E-mail: [email protected] Abstract— The diffraction fields and the shadow of standing tree diffraction are solved by using polygons to approximately take the place and approximation as approximate substitutes of for the circle. The algorithm model of ray path tracing is computed by tracing the ray path on standing tree. Considering el...
متن کاملHigher Order Equivalent Edge Currents for Fringe Wave Radar Scattering by Perfectly Conducting Polygonal Plates
-Two sets of higher order equivalent edge currents are introduced which, in combination, account for the first-, the second-, and part of the third-order edge diffraction caused by the fringe wave surface current induced on a perfectly conducting polygonal plate in a radar scattering configuration. The first set represents the fringe wave surface current excited by the incident plane wave at th...
متن کاملDiffraction by a right-angled impedance wedge: an edge source formulation.
This paper concerns the frequency domain problem of diffraction of a plane wave incident on an infinite right-angled wedge on which impedance (absorbing) boundary conditions are imposed. It is demonstrated that the exact Sommerfeld-Malyuzhinets contour integral solution for the diffracted field can be transformed to a line integral over a physical variable along the diffracting edge. This integ...
