An extension to the angular spectrum approach for modelling pressure fields of a cylindrically curved array transducer is described in this paper. The proposed technique is based on representing the curved transducer surface as a set of planar elements whose contributions are combined at a selected intermediate plane from which the field is further propagated using the conventional angular spectrum approach. The accuracy of the proposed technique is validated through comparison with Field II simulations.
本文描述了一种用于模拟圆柱形弯曲阵列换能器压力场的角谱方法的扩展。所提出的技术基于将弯曲的换能器表面表示为一组平面元素,这些元素的贡献在选定的中间平面上进行组合,然后使用传统的角谱方法从该平面进一步传播场。通过与FieldⅡ模拟结果进行比较,验证了所提出技术的准确性。
