Parallel Plate Capacitor System'rε =CAε0tLCR or ImpedanceAnalyzerDielectric Test Fixturetanδ =DAtThe first technique we will look at is the parallel plate capacitor technique.The sample is placed as the dielectric inside a parallel plate capacitor.Permittivity is calculated from knowing the area of the plate and thethickness of sample, and measuring the capacitance using an LCR orImpedance analyzer. In some analyzers the calculation is automated.29
