Review Questions
How do the dielectric constant and loss tangent affect the performance of materials used in terahertz applications?
The dielectric constant determines how well a material can store electrical energy when exposed to terahertz radiation, while the loss tangent indicates how much energy is lost as heat. Together, these properties influence how effectively a material can transmit or absorb terahertz waves. A higher dielectric constant typically means better energy storage capabilities, whereas a lower loss tangent signifies greater efficiency in energy use during terahertz interaction.
In what ways do the material properties of composites differ from those of their individual components when studied under terahertz radiation?
Composites often display synergistic effects where the combined properties exceed those of the individual components. Under terahertz radiation, these enhanced properties can lead to improved absorption or transmission characteristics that are critical for specific applications. Additionally, the interaction between different phases in a composite can reveal unique responses to terahertz waves that would not be observed in homogeneous materials, allowing for tailored applications in advanced technologies.
