Problem 1: The region
region
< 0 is occupied by plasma with dielectric permittivity ( ) = 1 −
while the
> 0 is a vacuum.
Show that along the plasma-vacuum boundary a surface wave can propagate in which the field strength
is damped exponentially with distance from the boundary. Find the frequency for which such a wave is
possible and its polarization. Restrict the discussion to that of a slow wave ( ≪ 1 ).
