EXACT SOLUTION FOR SCATTERING OF ELECTROMAGNETIC WAVES FROM BODIES OF ARBITRARY SHAPE .3. OBSTACLES WITH ARBITRARY ELECTROMAGNETIC PROPERTIES

The analytical technique developed earlier for the scattering of electromagnetic wave fields by perfect conductors is generalized to the case where the scattering obstacle is not only of arbitrary geometrical shape, but where both the scattering obstacle and the exterior environment have arbitrary, though homogeneous, electromagnetic properties. As before, the solution obtained is analytically exact and thus equally valid in the near and far zones, as well as over the entire frequency range. The special cases of the first-order solution and of an incident plane wave are considered in detail. The form of the solution is particularly well suited for methodical numerical evaluation. © 1969 The American Physical Society.
