TD-UAPO Diffraction by a Wedge Composed of PEC and Lossless Dielectric

摘要

This paper deals with the evaluation of the time domain electric field, which is diffracted by a perfect electrically conducting/lossless dielectric composite structure consisting of two adjacent acute-angled wedges with the edge in common. The involved diffraction coefficients are determined by applying the inverse Laplace transform to the corresponding Uniform Asymptotic Physical Optics diffraction coefficients in the frequency domain.
