Fabry-Perot resonator for permittivity measurement 60 GHz-330 GHz

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 the evaluation of low-loss dielectric materials at high frequencies up to 330 GHz, which cannot be covered by split-cylinder resonators. Traditionally the Fabry-Perot resonator was thought of as 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 a high frequency of 330 GHz, highly reproducible measurement results can be obtained regardless of the operator skills or installation environment.

About technical information, refer to "Resonator Method Technology Overview."

How to prepare your measurement sample, refer to "Proper sample preparation is the first step in accurate measurement."

Example: PP(38㎛) @ 220-330 GHz (J-band)

The sample was measured eight times, with it removed each time.High repeatablity at 300 GHz!

Measurement data: permittivity
Measurement data: tanD
