Hi, I was trying to simulate a periodic plasmonic structure and l used 1 nm mesh for most of my simulation region.
- when I looked at the power transmission of my bottom monitor, at certain wavelength the power flow is positive(meaning power flowing from outside into the fdtd region?). What caused this problem?
- I was using (1-reflection-transmission) to calculate the power absorbed in the structure but sometimes this gives Absorption greater than 1. I think this might come from problem1 but I was also wondering if this is a reasonable method to find the resonance for plasmonic structures.
