Abstract :
The paper offers the simple calculating characteristics of a cavity filled with arbitrary temporary dispersive homogeneous isotropic medium and obtaining electromagnetic fields. The theoretical consideration is in the frame of Evolutionary Approach to Electromagnetics in Time Domain. The resonator filled with the complex dispersive medium excited by wideband current pulse is considered as an example.
