Relative permittivity of gold at radio-frequencies

Click For Summary
SUMMARY

The relative permittivity of gold at radio frequencies, specifically between 15-20 MHz, can be modeled as a Perfect Electric Conductor (PEC). The conductivity of gold is established at 45.2 mega-mhos, which remains consistent until reaching the terahertz range. At higher frequencies, metals such as silver exhibit plasma-like behavior, indicating a shift in their electromagnetic properties.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with the concept of relative permittivity
  • Knowledge of Perfect Electric Conductors (PEC)
  • Basic principles of conductivity in metals
NEXT STEPS
  • Research the electromagnetic properties of metals at varying frequencies
  • Study the behavior of silver and other metals in the terahertz range
  • Explore the implications of modeling materials as Perfect Electric Conductors
  • Investigate the relationship between conductivity and permittivity in different materials
USEFUL FOR

Electrical engineers, physicists, and materials scientists interested in the electromagnetic properties of metals at radio frequencies.

What is the relative permittivity of gold at radio-frequencies or specifically around 15-20MHz?
 
Physics news on Phys.org
Model it as a PEC, if you really want to be specific though, wikipedia gives the conductivity as being 45.2 mega-mhos. The conductivity and permittivity will probably not change until you get into the terahertz range. Then, some metals, like silver I know, will behave as a plasma.
