85 Rb Rydberg atoms. This method may provide an independent, atom-based, SI-traceable
method for measuring mm-wave electric fields, which addresses a gap in current calibration
techniques in the mm-wave regime. The electric-field amplitude within a rubidium vapor cell
in the WR-10 wave guide band is measured for frequencies of 93.71 GHz and 104.77 GHz.
