qfdtd90

qfdtd90 is a free 3D FDTD code by yongxi Qian from UCLA. But I haven't the user's manual. Anyone can paste it here?
Thanks!

You can try to find the following reference:

Qian, Y. and T. Itoh, FDTD Analysis and Design of Microwave Circuits and Antennas (Software and Applications), Realize Inc., Tokyo, 1999.

Good Luck

good one
