Dear Lumerical Community,
I am wondering if my current mesh and simulation region sizes are properly set. I have created a cavity consisting of 4 beveled PEC plates with a TE polarized electric dipole source and am attempting to measure the power on the side of the cavity where the dipole source is located and compare it to the power on the opposite side of the cavity. I am trying to understand how large my mesh and simulation regions need to be in order to obtain the most accurate results.
Does my simulation region need to completely enclose the mesh region within it, or vice versa?
In conjunction, should I encompass my entire cavity structure in both the mesh and simulation regions?
Are the PML boundaries at the edges of the simulation region?
Attached is my current simulation file. What, if any, changes would one make within my file to ensure that the results I am obtaining are as accurate as possible?
