Recovering desired eigenfrequencies

Hi,

I'm performing an eigenfrequency analysis of a model in the Comsol 4.3a RF module. My problem is that, though I ask for only 1 eigenfrequency, Comsol ALWAYS gives me 2 eigenfrequencies: one purely real, and one complex. This is frustrating me because when I try to probe the eigenfrequency, it always probes the wrong eigenfrequecy (the complex one), so the only way I can extract the data for a 50 point sweep is to manually go through and extract the proper eigenfreq. The correct eigenfreq is always at the bottom of the dropdown menu, which in previous versions of Comsol always corresponded to the first solution.

I figure there are two solutions to my problem:

1. Figure out how to make Comsol only give me 1 eigenfrequency (should work if the bottom solution does still correspond to the first one it found).

2. Tell Comsol to probe eigenfrequency 1.

I can't seem to figure out how to execute either of these solutions. I'm attaching a couple screen shots of my model builder to help explain.

Any advice would be greatly appreciated.

Thanks, Chris
