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.

Microwave Dielectric Measurement System (Microwave Dielectrometer)

AET provides self-developed microwave dielectric measurement system (Microwave Dielectrometer).
It enables fast and non-destructive measurement of permittivity of thin-films and various dielectric materials. It has two types of measurement tools, which are the open coaxial probe type and the resonant cavity type.
