Extraction of coupling strengths for coaxial and waveguide resonators. (a) Coupling capacitance \(C_{{c}}\) (dots) obtained from an ABCD transmission matrix model fit to the measured spectrum versus the distance \(d_{{c}}\) between the center conductors of CC085Cu. The solid line is an exponential fit to the data. (b) Measured \(Q_{\mathrm{e}}\) of the \(\mathrm{TE}_{101}\) mode of a 3D cavity aperture coupled to a rectangular waveguide. The solid line is obtained from a finite element simulation.
