This book applies the four-dimensional formalism with an extended toolbox of operation rules, allowing readers to define more general classes of electromagnetic media and to analyze EM waves that can exist in them
- Formalism allows readers to find novel classes of media
- Covers various properties of electromagnetic media in terms of which they can be set in different classes
