Summary
The subject creates the basic laws of electric and magnetic fields. It is devoted to the study of electromagnetic wave propagation in different media: homogeneous, nonhomogeneous, absorbing, isotropis, and anisotropic. The special attention is oriented on the interaction of electromagnetic waves with interfaces. The final part is focused on modeling.
