Paper Abstract

The T-matrix or extended boundary condition equations due to Waterman have led to a method that can predict scattering from axially symmetric targets over a broad frequency range. Several studies have been performed for spheroids with interesting results. Interest in scattering from cylinders with hemispherical end caps has prompted us to analyze recent data from Le Havre. Much of the phenomena predicted by the T-matrix calculations are confirmed by the data we analyze. In addition, bending resonances are predicted by the theoretical calculations and are compared with predictions from beam theory. The systematics contained in the calculations strongly suggest that the excited waves are related to Rayleigh-type resonances studied on shells.
