Abstract
Our tin-tin oxide-tin tunnel junctions, when excited in their resonant electromagnetic cavity modes, exhibit quality factors as high as 660. This has allowed us to test Kulik's extension of Fiske-mode theory. We have verified his prediction that the dc current associated with a Fiske mode goes through a peak as increases, and we find his numerical value for the height of this peak to be correct. We find a small disagreement with his prediction of the value of the magnetic field that will maximize the dc current. We have also made some measurements of zero-field modes and of small, anomalous modes occuring at half-integral mode positions.
