H-polarized Plane Wave Diffraction by an Acute-angled Dielectric Wedge: A Time Domain Solution

摘要

This work deals with the time domain diffraction phenomenon originated by a penetrable acute-angled dielectric wedge when illuminated by a plane wave at normal incidence. In particular, the H-polarization case is here considered. The diffraction coefficients are determined in closed form via an inverse Laplace transform by taking advantage of the formulation of the frequency domain coefficients in terms of the transition function of the Uniform Theory of Diffraction. Then the transient diffracted field originated by an arbitrary function plane wave can be evaluated via a convolution integral.
