用精确代数方法在频域上求解了截断圆柱阵列对线性波的辐射和衍射问题。对于组合辐射和衍射，每个柱面上的边界条件由以阵列中每个柱面为中心的极坐标表示的几个傅里叶-贝塞尔级数的和来满足。然后将该方法应用于截断圆柱的正方形阵列，并给出了每个圆柱上的激励力，每个圆柱独立振荡时的附加质量和阻尼，以及由这种振荡引起的自由表面高度的结果。
The radiation and diffraction of linear waves by an array of truncated cylinders is solved in the frequency domain by an exact algebraic method. For combined radiation and diffraction, the boundary conditions on the surface of each cylinder are satisfied by the sum of several Fourier–Bessel series, expressed in polar coordinates centred on each cylinder in the array. This method is then applied to a square array of truncated cylinders, and results are given for the excitation forces on each cylinder, the added mass and damping for each cylinder oscillating independently, and free surface elevations resulting from such oscillations.
