Hi,
I was trying to reproduce the simulation results of T. Weiland et al. in the paper
T weiland et al. J. appl. Phys. Volume 90 Number 10 2001.
The authors try to simulate a split ring resonator (SRR) in MWS. I find that the results of the resonance frequency of the SRR are not very convincing. The authors place the SRR in a computational cell where they do not specify the dimensions of the latter. They only hint the boundary conditions!
I started with some rough cell size and found that the results are pretty much dependent on the computational cell size. If you change the later, you get some shifted results.
My question is:
If you have such a problem at hand, which cell size do you choose to obtain an accurate result? lamda, lamda/2,...??
What kind of surrounding space is good? Do we have to find it by trial and error?
Background properties:
->Surrounding space
lower x upper x (open boundary)
--- ---
lower y upper y (electric boundary conditions)
--- ---
lower z upper z (magnetic boundary conditions)
--- ---
Thanks for any insights.
