Paper Abstract

Reciprocal quantities are introduced in terms of the second moments associated with the near and far fields in wide- angle scalar wave propagation. Free fields are considered and conditions for the finiteness of the second moments are analyzed. Relations of the exact full-wave far field to the corresponding paraxial solution are established. Effects of polarization on wide-angle divergence are also briefly addressed.
