An alternative definition of the usual diffraction transfer matrix defined by Kagemoto and Yue (1986) has been developed. A method is thereby presented which enables the prediction of the diffraction transfer matrix for any desired wave frequency and water depth. The method has been tested for the case of a truncated vertical cylinder and the predicted matrix coefficients have been shown to be in good agreement with the analytical solution. Besides, post-processed quantities, such as the heave component of the excitation force, have been also considered for the comparison. The best results have been shown for the case of a fixed water depth condition and predicting for different wave frequencies. Furthermore, the investigations have shown promising results when only accounting for travelling wave modes.
