Abstract :
The time domain electromagnetic field evolution in the cavity filled with a homogeneous stationary but dispersive medium is investigated using the evolutionary approach to electromagnetics. The kernel of the constitutive relation integral part is chosen as the double-exponential function for dispersive medium description. The solutions for the free and forced oscillations are obtained in analytical form.
