Measurement Results
- Measurements are performed using a TM Resonator (1, 2, 5, 10 GHz), Split-Cylinder Resonator (10, 20, 28, 40 GHz), and Fabry–Perot Resonator (25–110 GHz).
- PTFE and Polycarbonate (PC) samples are measured with the corresponding resonators.

Key Point!
- With EM Labs products, measuring the same sample delivers consistent results!
- Verifying consistency across different fixtures is an effective way to confirm that the measured values from our instruments are highly reliable.
Unfortunately, since there is no globally recognized standard for permittivity, absolute accuracy cannot be strictly defined. However, by measuring the same material with multiple resonators based on completely different principles and calculation methods, you can verify whether consistent results are obtained. This provides a reliable basis for assessing the credibility of the measured values.
In this example, PTFE and Polycarbonate (PC) were measured using three different types of equipment. The results show consistent frequency characteristics, making it easy to evaluate material behavior. Even when the scale is greatly enlarged, the differences in measured values remain sufficiently small.
