We provide dielectric constant and magnetic permeability measurement service up to 330 GHz on a variety of samples including plates, films, liquids, and powders. Our turnaround time for results is typically 2 weeks from receipt of sample.
Fixtures: All of the resonator methods (Cavity Resonator, Split Cylinder, and Fabry Perot)
as well as S-parameter methods (Waveguide Sample Holder and Free Space) are available for professional measurement service.
In addition to dielectric constant and magnetic permeability, reflection and transmission characteristics are available on the S-parameter method.

Giving up evaluating powder or liquid? We have appropriate tools, knowledge, and techniques to measure dielectric constant accurately. Contact us for further details.
Liquid dielectric constant measurement example from 18GHz (K band) to 110GHz (W band) using free space.
THere is no discontinuities between bands.
Powder tan δ measurement example from 1GHz to 10GHz using cavity resonator. Sample C has frequency dependency.
Temperature dependency of dielectric constant is getting more and more important with growth of the application area of mmW devices.
We have a measurement service using a temp chamber (range: -50degC to 150degC) with a variety of split cylinders (freq range: 10GHz to 80GHz).
We have customized split cylinders for humidity tests for specific frequencies (10, 28, 40GHz) for range of temperature and humidity.
With a combination of temp dependency of dried condition, comprehensive understanding of the temperature and humidity dependency of material under the test. In the test example, samples of MPI (Modified Polyimide) and LCP (Liquid Crystal Polymer) are evaluated. First temp characteristics (-50degC to 150degC) for dried condition is characterized, then temp & humidity test added for range of condition. Difference of the behavior is clearly seen between these two materials.
