Abstract :
Inhomegeneous plane waves are used to represent 2D and 3D Green´s functions in free space. A special sampling scheme allows a compensation between aliasing and truncation errors. An error model is provided for the 2D and 3D cases. Very high accuracy is obtained with very few points in spectral domain, which confirms the sub-Nyquist nature of the approach.
