Abstract
A local impedance boundary condition for one-dimensional curved surfac es, applicable to a scattering formalism that permits the study of ree ntrant surfaces, is derived, The results are applied to the calculatio n of near- and far-field scattering patterns produced by a surface wit h a cylindrical cavity. The accuracy of the impedance boundary conditi on is evaluated with this example, which also illustrates the utility of the approximation.
