Exemplary waveguide resonator transmission spectra at room temperature. (a) Transmission coefficient \(\vert S_{21} \vert ^{2}\) versus frequency ν for CC141Al at RT. The dashed line indicates the frequency-dependent insertion loss on resonance \(IL(\nu_{\mathrm{n}})\). \(\vert S_{21} \vert ^{2}\) of (b) the first 6 measured modes and (c) 6 modes around \(8\ \mbox{GHz}\) as indicated by the dashed boxes in (a).
