Hi everybody,
+Problem: I want to simulate an square array of gold nanorings, in order to get the graphs for the transmittance and the reflectance and find the resonant frequency.
+My first approach:
-One box (Air) with one ring in the center (Au).
-A regular Port is ON on the top of the box (E=1,0,0) so it launches plane waves along Z. The waves will pass through the hole of the ring.
-Another regular Port is OFF on the bottom part of the box.
-The lateral walls of the box of Air parallel to X are PMC the perpendicular ones are PEC.
-I made a 1DPlot of
Reflectance= abs(emw.S11)^2
and
Transmittance=abs(emw.S21)^2
versus frequency
+Questions:
-How tall should I make my box to get an accurate result?
-I've read some post about people simulating similar structures by adding two PMLs (one at the top, one at the bottom of the box of Air). These people use a surface current to generate the plane waves. Is this method better/more accurate than what I'm doing?
Thanks in advance for your help!
