References for non-vacuum dispersion relations

Click For Summary
SUMMARY

This discussion focuses on the need for references regarding dispersion relations for photons and electrons in non-vacuum media. Key texts mentioned include "Introduction to Plasma Physics: With Space and Laboratory Applications" by D. A. Gurnett and A. Bhattacharjee, which provides a comprehensive derivation of dispersion relations, and the Jackson EM textbook, which covers essential aspects of electromagnetism. The conversation highlights the complexity of dispersion relations, emphasizing that factors such as molecular densities and electromagnetic fields significantly influence these relations.

PREREQUISITES
  • Understanding of Maxwell Equations
  • Familiarity with Fourier Transform techniques
  • Basic knowledge of electromagnetism
  • Concepts of plasma physics
NEXT STEPS
  • Research "Introduction to Plasma Physics: With Space and Laboratory Applications" by D. A. Gurnett and A. Bhattacharjee
  • Study dispersion relations in various media beyond vacuum

  • Investigate the impact of temperature and electromagnetic fields on dispersion relations
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism and plasma physics will benefit from this discussion, particularly those interested in the behavior of particles in non-vacuum environments.

Hi guys,

I'm looking for some references where dispersion relations, say for photons, are explicitely written out in a generic medium. In other words, the dispersion relation for particles not propagating in the vacuum is a different one than the standard vacuum one E^2 = p^2 + m^2 and I'm looking for papers/books where such relations are written out. Possibly for the photon or for electrons. Do you know any?

The Jackson EM textbook covers that and is very valuable for most aspects of EM with a bit of a bridge into QM and relativity. If you really want to dig into dispersion and see a full derivation you may want to look at a textbook on Plasma Physics such as Introduction to Plasma Physics: With Space and Laboratory Applications by D. A. Gurnett and A. Bhattacharjee. But that will require a working understanding of the Maxwell Equations and the Fourier Transform.

But unfortunately there is no generic medium. Molecular/atomic/ionic densities, particle trajectories, temperature and presence of EM fields, for example, all profoundly affect dispersion relations.
