[SI-LIST] Re: parallel plane strange results

Leonard,

The posted results look reasonable to me.  In parallel-plate resonators 
the peaks have
the same frequencies regardless of location (for lossless case; with 
losses, they shift
slightly).  Impedance minima, which look like series resonances, do change
significantly as you move over the planes.
