Abstract :
A numerical approach to the scattering problem of a plane electromagnetic wave at skew incidence on a wedge with two different arbitrary face impedances is presented. The diffracted field is obtained by applying the finite-difference method to solve two coupled parabolic equations. The present approach is validated by comparison with available asymptotic analytical results for the skew incidence case
