Abstract :
Excitation of electromagnetic fields by a wideband current pulse in a cavity filled with double negative dispersive medium and bounded by a closed perfectly conducting surface is studied. Some features of eigenfrequencies of such electromagnetic system are presented. Transient field evolution is shown.
