As high-speed and broadband communication systems become more and more common, there are greater demands for high-efficiency materials, especially dielectric materials having sufficient transmission characteristics. To meet these demands, 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.

Dielectric Measurement Service
Until now, measurements of the dielectric properties depend on the approximate calculations that are based on the perturbation theory. 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. We select the most suitable measurement method according to the size and shape of a sample material, and provide the measurement for almost all forms of samples including solid, sheet, film, multi-layered circuit board, particle and liquid.
