Remarkably easy and repeatable measurements even at 330 GHz
- Ideal for evaluation of low-loss dielectric materials with tan δ of 0.01 or less
- Automatic measurement in about 5 minutes to obtain the frequency characteristics in the frequency band
- Easy installation: Normal laboratory environment is sufficient
The Fabry-Perot resonator method is ideal for evaluating low-loss dielectric materials at high frequencies up to 330 GHz, which cannot be covered by split-cylinder resonators. Traditionally, the Fabry-Perot resonator has been considered a specialized instrument for a few specialists, but EM Labs has developed a solution that defies conventional wisdom by focusing on ease of use and repeatability in real-world applications. Even at the high frequency of 330 GHz, highly reproducible measurement results can be obtained regardless of operator skill or installation environment.

Measurement Examples
Sample size
Recommended sample size (Square) [mm]
| resonator | Lower limit | Recommended | Upper limit |
|---|---|---|---|
| E/W/D/G/J band | 45 | 50 | 55 |
| BroadBand | 60 | 65 | 94 |
Recommended thickness
The appropriate thickness depends on the dielectric properties and the resonator used, but 100 µm is a good rule of thumb. The higher the frequency and the higher the dielectric constant, the thinner the sample needs to be. The relationship between the sample thickness, dielectric constant, and frequency band is shown in the chart. The maximum sample thickness that can be measured correctly throughout the entire measurement frequency band of each device is shown in the chart. Please contact us for measurement of thicker samples. Note that a sample with high loss (tanδ>0.01 is a rough guide) requires an even thinner sample.
