Abstract
The surface impedance presented to a plane TE-wave by a wedge of high contrast is derived on the basis that the wedge possesses some absorption. It turns out that, over most of the surface of the wedge, the impedance is constant. The value of the constant coincides with that obtained by regarding a side as an infinite plane interface. Near the edge the impedance is no longer constant. Both the magnitude and phase can deviate substantially in this region from their asymptotic values. Nevertheless, the region of non-constancy is never large for the cases considered and does not extend beyond a free space wavelength from the edge.
