Need CPFDTD "Countour Path FDTD" Documentation

Hi,

is there any one who can provide me with links of documentation on the CPFDTD method, this method enable me to use nonrectangular cells for the FDTD simulation. i.e use another updates equations that take into account arbitrary shaped structures for simulation.

thanks for helping me.
