Product description
The dielectric constant of the plasma e(w) (see task (Obtain the formula for the dielectric constant e(w) of an ionized gas in a monochromatic electric field E = E0coswt. Neglect collisions of electrons and ions.)) is negative if w w0. In this case, the refractive index n = is a purely imaginary quantity. Find out the physical meaning of the purely imaginary refractive index.
