Choosing the Optimal Method for Testing Dielectric Properties of Materials
Every material has a unique set of electrical characteristics that derive from its dielectric properties. Accurate measurements of these properties can provide scientists and engineers with valuable information to properly incorporate a material in its intended application, thereby improving product designs and process quality.
A dielectric materials measurement can provide insight into critical design parameters for many electronics applications. For example, the loss of a cable insulator, the impedance of a substrate, or the frequency of a dielectric resonator can be related to its dielectric properties. The information is also useful for improving ferrite, absorber, and packaging designs. More recent applications in the area of aerospace, automotive, food, and medical industries also benefit from knowledge of dielectric properties.
