Abstract
This part of the paper deals with a variational approach. The general scheme is given and two examples are presented: free oscillations of a n electromagnetic field in a cavity filled with an inhomogeneous dispe rsive resonant medium and wave propagation in a longitudinally homogen eous plasma cylinder in an infinitely strong magnetic field. A compari son shows good agreement of results of a variational approach with res ults of an exact numerical solution. Possible ways of improving accura cy are discussed.
