摘要：

We describe a systematic method for obtaining the impedance boundary condition for a p- or s-polarized electromagnetic field at the curved boundary between vacuum and a metal as an expansion in powers of the skin depth of the field in the metal. The surface is defined by the equation x3 = ζ(x1), and the plane of incidence is the x1x3-plane. The first three terms in this expansion are obtained, and the conditions under which the result is valid are discussed. The boundary condition obtained is used in a determination of the dispersion curves for surface polaritons propagating across a one-dimensional metallic grating. © 1990.
