Abstract : The extended boundary condition equations due to Waterman have led to a T-matrix that can describe scattering from axially symmetric targets over a broad frequency range. Recent interest in scattering from cylinders with hemispherical end caps has prompted us to analyzed several examples from Le Havre. All phenomena predicted by the T-matrix calculations are confirmed by the data. In addition, bending resonances are predicted by the theoretical calculations and compared with predictions from bar theory. A series of predictions are made for various materials and aspect ratios to aid future experimental work.
