Hi everybody,
I have written an fdtd code and Have gotten result that I need, but I have a problems with understanding the near to far field transformation implementation in fdtd.I have read taflove book: Computational electrodynamics, the finite difference time domain method, publication of Luebbers on near to far field transformation and sullivan's book on electromagnetic simulation using fdtd, BUT i still have problem understanding the method.
My question is THIS: in evaluating the current densities on the virtual surface, how do I estimate the value of "f" in the superscript of the value of U(i.e the electric vector potential) or more precisely, how do i estimate the phase delay (tau subscrip d) and inco-orporate it into the progarm.
PLEASE: if anyone have a 3D near to far field transformation in FDTD, I will be very grateful if that person can post it. I NEED IT URGENTLY PLEASE. Thanks.
