Electromagnetic Diffraction by a Translating Multiple-Wedge Geometry

Peter De Cupis, Giorgio Gerosa

Abstract


The electromagnetic diffraction by a uniformly translating multiple-wedge geometry is
studied through the Frame Hopping Method: in the geometry rest frame the scattered field
is expanded as a multiple superposition of sets of Non-Integer Cylindrical Waves
(whose radial factor is expressed by non-integer order Bessel functions), where each
set is centered at one of the geometry vertexes; then, by exploiting Fourier representations
of cylindrical functions, the diffraction field is recast as a Plane-Wave spectrum;
this simplifies algebraic computations involved by relativistic covariance relations,
which are finally applied for recasting the solution in the observer frame.
