EXACT SOLUTION FOR SCATTERING OF ELECTROMAGNETIC WAVES FROM CONDUCTORS OF ARBITRARY SHAPE .2. GENERAL CASE

The perturbation-expansion technique developed earlier for the scattering of plane electromagnetic waves from cylindrically symmetric conductors is here generalized to an arbitrary radiation field incident on a conductor of entirely arbitrary shape. The analytical solution obtained is exact, inasmuch as no approximations, either of a mathematical or physical nature, were introduced. It is thus equally valid in the near and far zones, as well as over the entire frequency range, including the resonance region. Two separate analytical forms of the solution are obtained, and several special special cases are considered in detail. The form of the solution is particularly well suited for methodical numerical evaluation by machine calculation. © 1968 The American Physical Society.
