3D FDTD with UPML and TFSF plane wave

I need help with my project.
i have code for 3D FDTD with UPML but I don't know
how to add the TFSF plave wave
I have code for 2D TFSF but I don't understant it and don't know how to translate
it for 3D(see the file here)
also i look at here:
https://www.edaboard.com/viewtopic.p...highlight=tfsf
and need help to understand it

please help

you can show sulivan book "Electromagnetic Simulation Using the FDTD Method (IEEE, 2000)(pp176)" and Taflove book "Computational Electrodynamics FDTD" sulivan give simpl explication tfsf and the porgramme in 3d whith pml and tfsf with plane wave and taflove book is very very important book to anderstand fdtd if you dont have this book give me your mail and i send them to you

I want the book <The Finite Difference Time Domain Method for Electromagnetics: With MATLAB Simulations>, do you have it? Can you share it with me. My email is chaiyanjie2005@163.com. Thank you !
