I’ve got a system of rods here:
…that I want to model as an infinite array of rods. I’ve place Periodic BCs in the x and y directions, and PML in the z directions. The source is a standard plane wave. Mesh refinement in the middle
When I run the simulation the results don’t look periodic on the sides. It looks as if the E field doesn’t recognize that there should be another pillar to interact with directly to the left/right of it. Am I misunderstanding something in how these simulations work?
Thanks for any help
