摘要
A high-frequency acoustic field in a penumbra domain on the surface of a strongly elongated body is investigated. A new asymptotic formula expressing the field in the form of inverse Mellin transform of an expression containing Whittaker functions is derived. Presented numerical results show that the increase of the transverse curvature of the body increases field attenuation on a hard surface and decreases it on an acoustically soft surface. This effect agrees to previous results.
