Interested in electromagnetic waves inside plasmas with known dielectric properties, we prove that Courant-Hilbert fields of the focus wave mode type can propagate in a steady-state, isotropic, neutral plasma which is in fact a dielectric with the refractive index where is the plasma frequency. We also prove that neutral, isotropic plasmas with memory behave for harmonic plane waves as a time reversal mirror when the memory function is a decreasing exponential.
