The dielectric constant (usually denoted by ε) and the loss tangent (tanδ) are key parameters that describe the electromagnetic properties of materials. They are crucial for understanding how materials interact with electromagnetic fields. The importance of these parameters is reflected in the following aspects:
Electromagnetic Field Influence and Energy VariationThe real part of the dielectric constant (ε') represents the material's ability to store electromagnetic energy, while the imaginary part (ε'') reflects the degree to which the material dissipates electromagnetic energy. Together, these two components provide insight into the material's behavior in an electromagnetic field. |

Material Selection and OptimizationUnderstanding a material's dielectric constant and loss tangent helps in selecting the best candidate from a wide range of materials, and also provides guidance for the design of new materials. For example, to improve the performance of a certain electronic device, it may be necessary to choose a material with a specific dielectric constant value for use as a substrate or other components. In summary, testing of the dielectric constant and loss tangent not only enables researchers to gain a deeper understanding of a material’s fundamental physical properties, but also plays an irreplaceable role in driving technological innovation and development across multiple industries. |
