Abstract
In trying to implement temperature compensation of high-Q metallic microwave cavities with the two-metal technique, crippling problems arise from the exceedingly high uncertainty with which the Coefficients of Thermal Expansion (CTE) of the two metals are known, and from their non linearity with temperature. A novel approach is here proposed, following which both problems can be separately addressed, opening the way for improvement of the resonance frequency temp-co into the 10^-10/K and possibly the 10^-11/K region.
