How to Measure Material Permittivity and Permeability

+ Impedance Analyzer

Characterize Material Properties Across Frequency

Characterizing dielectric and magnetic materials requires measuring their electrical response across frequency under controlled test conditions. Permittivity describes a material's response to an applied electric field, while permeability characterizes its response to a magnetic field. An impedance analyzer combined with an appropriate material fixture provides the impedance measurements needed to derive these complex material properties.

Frequency-swept measurements reveal changes in the real and imaginary components of permittivity or permeability as well as associated material losses. Engineers can use these measurements to characterize frequency-dependent behavior, compare candidate materials, and evaluate dielectric or magnetic properties under defined measurement conditions. The fixture and measurement method are selected according to the material property being characterized.

Material Permittivity and Permeability Measurement Solution

Measuring material permittivity and permeability requires an impedance analyzer, an appropriate material fixture, and a measurement configuration suited to the material under test. Keysight ZA5 Impedance Analyzer provides frequency-dependent impedance measurements that can be used to characterize dielectric and magnetic material properties. With an appropriate fixture, engineers can evaluate complex permittivity or complex permeability and examine the corresponding material losses across frequency. Swept measurements reveal frequency-dependent material properties, enabling quantitative comparison of dielectric and magnetic materials.
