摘要：

Asymptotic expressions for the fields scattered by an anisotropic impedance wedge at oblique incidence are derived in the context of the uniform geometrical theory of diffraction (UTD), They are obtained by resorting to a perturbative approach, considering the normal incidence case as the imperturbed configuration. We observe that the limits of applicability of this approximate analytical solution extend far beyond those of standard perturbative approaches, allowing us to account for deviations from the normal incidence case of 20 degrees to 30 degrees.
