Wavefront and resonance analysis of scattering by a perfectly conducting flat strip
Abstract
Transient scattering by a perfectly conducting flat strip is analyzed by successive wavefront tracking for both H- and E-polarized impulsive plane wave incidence. A ray expansion based on the geometrical theory of diffraction is constructed in the frequency and time domains, and the resonance representation is found by collective summation of the multiple diffracted ray fields. The hybrid wavefront-resonance formulation is developed by partial collective treatment of the ray fields.
