Modelling of Scattering by Partially Buried Elastic Cylinders

Abstract

The work of a previous memorandum on the modelling of scattering by a partially buried cylinder is extended to allow the cylinder to have full elasticity (and not just be a fluid structure as in the previous work). The results of computations showing the effects of increasing burial on the backscattered field, both in the spectral and temporal domains, are given. A shelled and a solid aluminum cylinder are considered for a grazing angle of incidence which is subcritical.
