| Abstract: | Microwave complex permittivity of PTFE (Teflon) was measured using a transmission/reflection (TR) method and a coaxial sample fixture. A range of sample dimensions were prepared in order to examine the effect of airgaps on the measured permittivities. The measurements were compared with calculated values using a formula derived by considering the total capacitance |
