References for non-vacuum dispersion relations

  1. Mar 10, 2010 #1
    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 [tex]E^2 = p^2 + m^2[/tex] 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.
