This dataset demonstrates a method for temperature correcting microwave cavity perturbation measurements by monitoring two modes; one which is perturbed by the sample and one which is not (referred to as a nodal mode). The nodal modes used (TM310 and TE311 for an axial sample in a cylindrical cavity) are subject only to sample-independent influences. To demonstrate this technique the bulk permittivity of a PTFE rod has been measured under varying temperature conditions. The results show that without correction, the measured temperature dependent dielectric constant has large variations associated with the stepped and linear temperature ramping procedures. The corrected response mitigates systematic errors in the real part. However, the correction of the imaginary part requires careful consideration of the mode coupling strength. This work demonstrates the importance of temperature correction in dynamic cavity perturbation experiments.
