FTDT ABC not absorbing at boundaries

I’ve been following along the “Understanding the Finite-Difference Time-Domain
Method” By John B. Schneider and generally practicing python along side my understanding of FDTD. I have so far be able to keep up and understand whats going on and what I was doing wrong, but I am currently at chapter 8.6 and struggling with getting my ABC to work at all. I am not sure whether it is a problem with my TFSF boundary or just the ABC alone. When I run the simulation as the source reaches the boundary it will just reflect off it without being absorbed at all. My end goal now is to just be able to reproduce figure 8.6.
