Dielectric Measurement Service

Now that high-speed and broadband is becoming ever more widespread, intense demand rises for high-efficiency materials. To meet the demand, it's pivotal to analyze characteristics of materials, especially to perform dielectric measurements. AET, Inc. with our experience and expertise in the fields of microwave and millimeter-wave, provides you with services for dielectric measurements.

The dielectric measurement service offered by AET, Inc. uses a high Q cavity and 3D electromagnetic field simulation technique into the process of measuring the dielectric properties. This allows us to accurately compute the complex value of relative dielectric properties of a sample.
For each sample material, the most suitable measurement method will be selected according to its size and shape. Almost all forms of samples are measurale, e.g. solid, sheet, film, multi-lavered circuit board, particle and liquid.

Applications

  • Substrate materials for high-speed digital and microwave circuits
  • Low loss dielectrics used for filters and dielectric antenna
  • Thin film materials
  • Semiconductor materials
  • Medical Electronics
  • Chemicals
  • Foods(moisture content)
  • Body tissues
  • Gases
  • Liquids
