Gold's index of refraction in micro-onde

Click For Summary

Discussion Overview

The discussion revolves around the index of refraction of gold at microwave frequencies, specifically at 10 GHz. Participants seek values and resources related to this property, exploring various references and potential contacts for accurate information.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the index of refraction of gold at 10 GHz and requests resources for this information.
  • Another participant suggests contacting NIST or other metrology labs for assistance in obtaining the value.
  • A participant mentions having a contact at NIST but still lacks the specific index of refraction value.
  • One participant points to a website, refractiveindex.info, as a potential resource for finding refractive index values.
  • However, there is a concern that the values available on the suggested website are limited to optical wavelengths in micrometers, not applicable to the microwave range.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific index of refraction value for gold at 10 GHz, and there are multiple suggestions for resources, indicating ongoing uncertainty and exploration of the topic.

Contextual Notes

There are limitations regarding the availability of refractive index values at microwave frequencies, and the discussion highlights the challenge of finding relevant data that is not confined to optical wavelengths.

Are there someones know about gold's index of refraction in micro-onde, for exemple in frequency 10GHz? Or a book in which I may find the value. Thanks a lot.
 
Science news on Phys.org
Thanks Andy, I've got contact with a guy at NIST who works at GHz.
Still, I don't have that value...

I have also the paper in your third link, but obviousely all the values are given in optical field, knowing that the wavelength of GHz is in mm.

Hi zoe101,

Have you checked out http://refractiveindex.info/?

Claude.

Thank you Claude. It's a very good link. However, the wavelength is limited in µm.
