    Hi

    I was wondering if anyone had a quick and dirty approach on near field to far field transformations - without worrying about probe corrections

    I am just interested in implementing a code for planar NF-FF for tangential E field measurements in a plane to see how the transform works. I dont really need to worry about probe correction.

    I have done substantial reading and written my own code but my far field pattern seem to be off as compared to simulation from commercial codes.

    The algorithm I used is
    1. Read NF data (Tangential E-field)
    2. Implement a DFT
    3. Identify FF 'cuts' for the the \theta and \phi angles
    4. Calculate FF using DFT

    Is anything wrong with this
