E-polarized electromagnetic diffraction by a composite wedge, II:Extended diffraction coefficients

도체와 유전체가 복합된 쐐기에 의한 E-편파된 전자파의 회절, II:확장된 회절계수

The physical optical solution to the E-polarized diffraction by a composite wedge consisting of perfect conductor and lossless dielectric cannot sayisfy not only the boundary conditions at the wedge interfaces but also the edge condition at the wedge tip. Its diffraction coefficients are extended outside the composite wedge to become the exact solution to the perfectly conducting wedge as its relative dielectric constant increases to infinite or decreases to 1. It is assured that the extended diffraction coefficients approach zero in the arificially complementary region of the composite wedge.
