A major step in the computation required to transform a plane-polar near-field into the far-field is the Hankel transform. One of the simplest ways to circumvent numerical Hankel transform evaluations is the interpolation method which converts the polar grid to a rectangular grid. This method turns out to be the most efficient plane-polar near-field to far-field transformation method.
