The unexpected 12.086 GHz mode is clearly seen.

Simulation of the full-size PETS with GDFIDL
Low frequency trapped modes.
The equivalent radius for the PETS trapped modes
Re15.14 mm was defined for the
given frequency of the lowest mode -12.086 GHz
and fixed wavelength 1.0 m. The simulations with
HFSS confirmed that at least 3 modes are nicely
trapped.
