far field matlab

Hello everyone, I'm trying to implement Near to Far field transformation (frequency domain) for my fdtd code in matlab following taflove's books but it doesn't work.
I honestly don't understand where I'm doing wrong because I'm following the books step by step.
Does anybody have a 3D/2D working code and be so nice to share it?
( cb88(et)hw.ac.uk )

Kind regards

That's just what I need so much!

Hi deltisme,
the file you uploaded is about FFT with desired frequency resolution, perhaps a mistake?

cheers
 

far field transform code fdtd

you can use two other books the first one written by sullivan and described codes in matlab and step by step and the second one written by kunz which describes the concepts excellently

Hi
This code doesn't do any NF to FF transform. It is simply an FFT transformer.
The NF to FF transformation equations are very compelcated.
