Relationship between the phase and group velocity in a conducting medium

Click For Summary
SUMMARY

The relationship between phase velocity (vφ) and group velocity (vg) in a conducting medium, specifically in plasma, is defined by the equation vφvg = v2 = 1/(με). This equation holds true in plasma as well as in other conducting media. The parameters μ (permeability) and ε (permittivity) are critical in determining the propagation characteristics of electromagnetic waves. Understanding this relationship is essential for analyzing wave behavior in various conducting environments.

Is the relation v_{\varphi }v_{g}=v^{2}=\frac{1}{\mu \varepsilon } always true in a plasma ?
Where v_{\varphi }, v_{g} are respectively the phase and group velocity of the electromagnetic wave that is propagating in the plasma.

I said in a plasma but it could be in any conducting medium.
