“…Henry et al [24] studied polymer latex coalescence by dielectric measurements at microwave frequencies using a cavity perturbation technique. Akyel and Bosisio [25] suggested a cavity perturbation technique in which high-temperature measurements can be performed. For the measurement of the complex permittivity of highly polar liquids such as water, Mathew and Raveendranath [26] proposed a new cavity perturbation method.…”

“…Material parameters have been measured for decades with samples placed in cavities [5][6][7][8]. The scattering parameter spectra of the microwave one-or two-ports formed by the cavities, together with appropriate coupling structures, are measured with scalar or vector network analyzers (VNAs).…”

The microwave cavity perturbation method is widely used for material parameter measurements in connection with small homogeneous samples. Its applicability to larger and inhomogeneous samples is uncertain, but highly desirable in connection with the in- situ condition monitoring of chemical reactors. We have investigated the problem of the reconstruction of axially inhomogeneous permittivity distributions in tubular reactors from measured cavity resonance frequencies of the reactor. It is shown that the use of a priori knowledge about the function class of the permittivity distribution, which in turn follows from assumptions about the chemical process inside the reactor, allows one to reconstruct the permittivity distribution based on a few resonances only. The resulting errors in the function parameters or in the permittivity values identified are on the order of 5%, as demonstrated by analytical and numerical calculations, by numerical experiments, and by laboratory experiments.
