Abstract :
Ray behavior and the corresponding fields in the vicinity of surface-curvature-induced reflection boundaries are examined and compared with edge-induced reflection boundaries. The slopes of the reflection boundaries vary, respectively, as (\\lambda )^{-5/6} and (\\lambda )^{-1/2} . Asymptotic evaluation of the physical optics scattering integrals leads to the definition of equivalent "diffrhction" coefficients involving the Airy function.
