Scattering of plane wave on cylindrical shell in low-frequency region
Abstract
The scattering amplitude of a plane wave striking an infinite cylindrical shell at an arbitrary angle in the low frequency region is analyzed. It is found that resonant properties of an infinite cylindrical shell in water will be observed in the scattered field only for shells with thickness of n/R 0.0004 (for steel). No resonance will be noted in the scattered field for inner shells. The introduction of additional losses reduces the scattering amplitude at resonance, and the resonance properties become significant as the shell becomes thicker.
