Abstract

Expressions are derived for the far field that results when electromagnetic radiation is incident upon an imperfectly conducting nonhomogeneous plane surface. In particular, these expressions include the second-order far field and thus allow consideration of surface wave effects. It is shown that the far field satisfies an integral equation and this is used to study the field resulting from a dipole that sits above a finite ground screen
