Diffraction of Plane Wave by Dielectric Wedge

A physical optics (PO) solution is obtained analytically for the fields scattered by a dielectric wedge for plane wave incidence. One may correct PO solution by making the extinction integrals along the interface boundaries vanish in their complementary regions by adding correction boundary fields to the PO solutions along the interface boundaries. The correction boundary fields may be constructed as the multiplication of the field satisfying the static edge condition, the dynamic plane wave dependence satisfying the phase variation of the incident, reflected, and refracted plane waves of PO solutions, respectively, and the pattern function canceling the edge-diffracted wave pattern of each plane waves of PO solutions.
