near field t0 far field code

Do you have access to Sullivan's FDTD book? The code for this is in there. I have not ever written the near-to-far field transformation or I would just send you that. If you give me your e-mail address, I could perhaps send you whatevermaterials I have.

-Tip

For the standard methods you can use any of the three text books.

- Taflove
- Sullivan
- Kunz&Luebbers

(searching google with the names above and FDTD should give you links to the books)

For a more accurate method look at

http://www.eecs.wsu.edu/~schneidj/journal.html

and download the paper:

# D. J. Robinson and J. B. Schneider, "On the Use of the Geometric Mean in FDTD Near-to-Far-Field Transformations," IEEE Trans. Antennas Propagat. vol. 55, no. 11, pp. 3204--3211, 2007. (336 kB PDF file.)

PS. Don't trust the code in Sullivan's book. There are a number of errors (some parts even don't compile). Furthermore it is not easy to modify his code. Writing your own code from scratch is
probably faster.

anyone please help me...

I would appreciate it if anyone could help send me near-to-far-field transformation matlab code.

Have you ever tried the huygens principle ,it should works
